try changing this to

fprintf(f,"atdt82,,%s\n",number); //Commas are to tell the modem to wait,
then dial the number
You usually need to wait for a 2nd dial tone when dialing outside of a PBX.

fprintf(f,"+++ ath0\n"); //+++ is to to tell the modem to switch to command
mode, then execute the command.
Which if I remember correctly is ath0. It's been a while since I've done any
stuff w/ modems. Used to use BBSes, but it's been about 4-5 years. Also, \n,
which is the new line, might work better as ^M, literal caret and then M.
Modems interpret this as control-m, which is a linefeed.

Also, all of this info is given to you w/o the benefit of an actual modem in
my computer. It is all from my memory of the days when I used to use BBS
systems.
