9.4 Sending a Fax

You can send a fax from your cell
phone if both your cellular carrier and your cell phone support it.
You can figure out quickly whether your phone supports it by making a
Kermit connection (see Section 9.3
earlier in this chapter). Here's a session with a
Motorola v120e in which the phone acknowledges that
it's capable of Class 2 fax modem commands:

bjepson@debian:~$ kermit -l /dev/ttyACM0 -b 115200
C-Kermit 7.0.196, 1 Jan 2000, for Linux

Type ? or HELP for help.
(/home/bjepson/) C-Kermit>connect
Connecting to /dev/ttyACM0, speed 115200.
The escape character is Ctrl-\ (ASCII 28, FS)
Type the escape character followed by C to get back,
or followed by ? to see other options.
----------------------------------------------------
AT+FCLASS=?
0,2.0
OK

However, the following session with the Nokia 6200 shows that it
doesn't have any fax modem capabilities:

bjepson@debian:~$ kermit -l /dev/ttyUSB0 -b 115200
C-Kermit 7.0.196, 1 Jan 2000, for Linux
Copyright (C) 1985, 2000,

Type ? or HELP for help.
(/home/bjepson/) C-Kermit>set carrier-watch off # required for some phones
(/home/bjepson/) C-Kermit>connect
Connecting to /dev/ttyUSB0, speed 115200.
The escape character is Ctrl-\ (ASCII 28, FS)
Type the escape character followed by C to get back,
or followed by ? to see other options.

OK

To send a fax with your cell phone, install a package such as
efax
(http://www.cce.com/efax/) and
configure it for your modem. In the case of efax, you must edit
/etc/efax.rc. At a minimum, you should set the
device (DEV), your phone number (FROM), and name (NAME):

DEV=ttyACM0
# Your fax number in international format, 20 characters maximum.
# Use only digits, spaces, and the "+" character.
FROM="+1 401 555 1234"
# Your name as it should appear on the page header.
NAME="Brian Jepson"

Once you've done this, you can use a client program,
such as fax (included as part of the efax
package), to send a file:

bjepson@debian:~$ fax send 4015555678 Letter.ps 
Letter.ps is postscript or pdf ...
