Fax out from linux machine

Some time ago I recycled my FAX machine for space and obsolesce reasons. Recently I had to transmit some sensitive documents that needed encryption. I encrypted them using 7zip+AES256. Unfortunately the receiver was not able to decrypt them even after several rezip-decrypt attempts. The receiver couldn't even decrypt self decrypting archives :-(.

Only means of communication was FAX.

Currently I use Dell D430 with Xubuntu 12.04.1 LTS. Unfortunately, the laptop's inbuilt modem is not recognized by the OS. After some searching I found a USB modem that was supposed to work on Linux. It was Trendnet TFM-561U that is currently available from online and local retailers. I was able to find it in a local store and decided to give it a try.



I connected the modem to my laptop and it popped up in dmesg as /dev/ttyACM0. I quickly installed minicom and connected to the modem using device ttyACM0. The modem responded "OK" to Hayes AT commands. This concluded that the modem works with the OS and hardware.

Next step was to install the fax software. Because of popularity I chose to install efax-gtk. I also installed the efax (command line tools). Efax-gtk was pretty easy to configure.
