Providing you know what com port the modem is on (probably 3 or 4 if it's an internal modem) you can fire up a program called minicom (similar to hypertrm) and issue some at commands to the modem. Make sure that you have the symlink in place for /dev/modem prior to doing this
#cd /dev
# ls -la modem*
If the symlink isn't there you can create it by using the following command
#ln -s /dev/ttyS2 /dev/modem (providing the modem's on com3) or
#ln -s /dev/ttyS3 /dev/modem (if the modem's using com4)
If all's working well you should be able to see some initialisation strings come on the minicom screen when it starts up. Try typing at&v from within minicom.
