Take a look on this post: http://frontlinesms.ning.com/forum/topics/installing-frontlinesms-on
The relevant bit starts:
Get to the folder /dev/ and use # ls to view the files in that folder. Having plugged the modem into your computer, you should see something like ttyACM0 as a port. This is great, it means the computer is seeing your modem. If you're using the Falcom GSM Samba 75 modem, this will happen automatically - you don't have to load the drivers or anything.
FrontlineSMS will be looking for it on ports /dev/ttyS0 and /dev/ttyS1
But your modem may be on port ports /dev/ttyACM0, for example.
So create a symbolic link to make the one look like the other:
# sudo ln -sf /dev/ttyACM0 /dev/ttyS0
Hi Tichafara, Thanks for this message. As we would like to have an affordable device which works with both FrontlineSMS and FreedomFone, your message is of interest. I notice MobiGater has drivers for all 32bit Windows OS. How difficult was the initial Windows configuration of FrontlineSMS? Doable for the non-techie? Thanks!
