/dev/cua1 on the second ring. This device will be locked using two different lock files but these lock files will be removed while waiting for incoming calls (-s). If a data call is detected, the getty program will be run to initialize the terminal driver and start a login(1) process. Received fax files will be stored using names like Dec02-12.32.33.001, in the /usr/spool/fax/incoming directory and the log file will be appended to /usr/spool/fax/faxlog.cua1.

efax -d /dev/cua1  -j '+FAA=1' \
   -x /var/spool/uucp/LCK..cua1 \
   -x /var/spool/uucp/LCK..ttyS1 \

   >> /var/spool/fax/faxlog.cua1 2>&1

Note that adaptive answer of either type will not work for all callers. For some data calls the duration of the initial data-mode answer may be too short for the initial handshaking to complete. In other cases this duration may be so long that incoming fax calls will time out before efax switches to fax mode. In addition, some calling fax modems mistake data-mode answering tones for fax signaling tones and initiate fax negotiation too soon. If you use software adaptive answer you can reduce the value of the initial data-mode answer (set by TO_DATAF in efax.c) to get more reliable fax handshaking or increase it for more reliable data handshaking. However, if you need to provide reliable fax and data service to all callers you should use separate phone numbers for the two types of calls.

When a call is answered the modem goes on-line with the computer-to-modem baud rate fixed at the speed used for the most recent AT command. When efax is waiting for a fax or data call it sets the interface speed to 19200 bps since this is the speed required for fax operation. This prevents full use of 28.8kbps modem capabilities.

 

init¸¦ »ç¿ëÇÏ¿© efax ½ÇÇàÇϱâ

efax can answer all incoming calls if you place an entry for efax in /etc/inittab (for SysV-like systems) or /etc/ttytab (for BSD-like systems). The init(8) process will run a new copy of efax when the system boots up and whenever the previous process terminates. The inittab or ttytab entry should invoke efax by running the fax script with an answer argument.

For example, placing the following line in /etc/inittab (and running "kill -1 1") will make init run the fax script with argument answer every time previous process terminates (and init is in runlevel 4 or 5).

s1:45:respawn:/bin/sh /usr/bin/fax answer

For BSD-like systems, a line such as the following in /etc/ttytab will have the same effect:

ttya "/usr/local/bin/fax answer" unknown off

You should protect the fax script and configuration files against tampering since init will execute them as a privileged (root) process. If you will be allowing data calls via getty and login you should ensure that your system is reasonably secure (e.g. that all user id's have secure passwords).

If efax exec()'s getty properly but you get a garbled login prompt then there is probably a mismatch between the two ends of the serial link between the modem and the computer. First, check the efax log file to make sure the modem's CONNECT response reported the serial port speed (e.g. 19200), not the modem-modem speed (e.g. 14400). Next, check the getty options and/or configuration files (e.g. /etc/gettydefs) for that particular baud rate. Then run getty manually with the same arguments and verify the port settings using ``stty </dev/XXX''. Note that you'll probably want to enable hardware flow control for data connections (-h for agetty, CRTSCTS for getty_ps).

A few programs won't work properly when efax is set up to answer calls because they don't create lock files. You can put the shell script ``wrapper'' below around such programs to make them work properly. Change BIN and LOCKF to suit.

#!/bin/sh
BIN=/bin/badprogram
LOCKF=/var/spool/uucp/LCK..cua1
if [ -f $LOCKF ]
then
        echo lock file $LOCKF exists

You can add a "fax" printer to the lpr print spooler that will fax out a document using efax instead of printing it. This allows a network server running efax to send faxes on behalf of other machines, including non-Unix clients. In the following steps use the directories specified in the fax script if they are different than /usr/bin and /var/spool/fax (FAXDIR). To set up a fax printer:

(1) Create a link to the fax script called ``faxlpr'' so the fax script can determine when it is being invoked from the print spooler:

ln -s /usr/bin/fax /usr/bin/faxlpr

(2) Edit /etc/printcap and add an entry such as:

fax:lp=/dev/null:sd=/var/spool/fax:if=/usr/bin/faxlpr

to define a printer called "fax". Print files will be spooled to the /var/spool/fax (sd=) directory and then piped to the /usr/bin/faxlpr filter (if=).

(3) Create and/or set the permissions on the fax spool directory. For example:

mkdir /var/spool/fax
chmod ugo=rwx /var/spool/fax

You should now be able to send a fax using the lpr interface by using a command such as:

lpr -P fax -J "555 1212" file.ps

where the -J option is used to specify the phone number or alias to be dialed.

Note that if more than one file is given on the command line they will be concatenated before being passed to "fax send". TIFF-G3, Postscript or PBM files must therefore be sent one file at a time although the TIFF and Postscript file may contain multiple pages. Only multiple text files can be sent in one command. Page breaks in text files can be marked with form-feed characters. Files will be converted and sent at the default (high) resolution.

You can use lpq(1) to check the fax queue, lprm(1) to remove fax jobs and lpc(8) to control the spooler. In each case use the -Pfax option to specify the fax ``printer.'' A log file will be mailed to the user when the fax is sent.

You should also be able to send a fax from any networked computer that has lpr-compatible remote printing software and that allows you to set the job name (-J option) to an arbitrary string. Such software is available for most computers.

See the lpd(8) and printcap(5) man pages for information on the print spooler and for restricting access by host name (/etc/host.lpd) or by user group (the `rg' printcap entry).

Double check the configuration setup in the first part of the fax script.

Run the "fax test" script to check the modem's responses to various commands. The results will be displayed at the end of the test. Some ERROR responses from the modem should be expected since most modems don't implement all the possible commands.

If efax hangs when trying to open the modem device (typically ttyX), the device is either already in use by another process (e.g. getty) or it requires the carrier detect line to be true before it can be opened. Many systems define an alternate device name for the same physical device (typically cuaX) that can be opened even if carrier is not present or other programs are already using it.

If modem responses are being lost or generated at random, another processes (e.g. getty or an efax auto-answer process) may be trying to use the same device at the same time. Using lock files (-x options) can often resolve this problem.

Check the response to the "AT+FCLASS=?" command to make sure your modem supports the Class (1, 2 or 2.0) that you have selected. If you have a Class 1 modem, check the response to the "AT+FRM=?" command to verify the speeds supported (e.g. a response of "24,48" would mean only 2400 and 4800 bps are supported). For Class 2 modems check the response to the "AT+FDCC=?" command to make sure the modem supports the capabilities you have selected (see CAPABILITIES above).

Attempt to send a fax. Check that the modem starts making the calling signal (CNG, a 0.5 second beep every 3 seconds) as soon as it's finished dialing. This shows the modem is in fax mode. You may need to use the option -iM2L3 to monitor the phone line (see the SPKR string in the fax script).

Listen to the answering fax machine and check that it sends the answering signal (CED, a 3 second beep) when it answers followed by "warbling" sounds (DIS frames) every 3 seconds. If you hear a continuous signal instead (tones or noise), then you've connected to a data modem instead.

Your modem should now send back another warble (DCS frame) immediately followed by 1.5 seconds of noise (a channel check). If everything is OK, the receiving end will send another warble (CFR frame) and your modem will start to send data. If you have an external modem check its LEDs. If flow control is working properly the modem's send data (SD) LED will turn off periodically while the fax data is sent.

When the transmission completes, check the message showing the line count and the average bit rate.

Low line counts (under 1000 for a letter size image) or the warning "fax output buffer overflow" when sending indicate that the image data format is incorrect. Check the file being sent using the "fax view" command.

If you get the error message ``flow control did not work'' then flow control was not active. This usually results in a garbled transmission and the receiving machine may reject the page, abort the call, print a distorted or blank image and/or hang up.

Most modems enable XON/XOFF flow control when fax mode is enabled. Check the output of the fax test command for the flow control settings in fax mode (typically &K4 or \Q1). If they are incorrect you can use -j commands to enable flow control.

The warning "characters received while sending" or an <XOFF> character appearing after the transmission means that the operating system ignored the modem's XOFF flow control character. Ensure that you are not running other programs such as getty or pppd at the same time as efax since they will turn off xon/xoff flow control.

If you cannot get flow control to work properly then enable ``virtual flow control'' with the -of option.

Check that the remote machine confirms reception with a +FTPS:1 response (Class 2) or an MCF frame (Class 1).

For Class 2 modems, the error message "abnormal call termination (code nn)" indicates that the modem detected an error and hung up. The modem's manual may give an explanation for the error number nn.

Many companies advertise services that will fax back information on their products. These can be useful for testing fax reception.

The message "run length buffer overflow" when receiving indicates an error with the image data format -- make sure you are using the -or option with Class 2 modems.

If efax should display the message "can't happen (<details>)" please send a bug report to the author.

Finally, don't play "option bingo," if you can't resolve the problem save the output of the fax test command to a file (e.g. fax test >test.out) and send it along with a verbose log of the failed session to the address below. If you don't get a response in a reasonable time try the mailing list described below.
