Under Real Mode MSDOS, you should be able to echo commands to a hardware
modem from the commandline but not to a winmodem. You *must* boot in MSDOS
mode rather than using a windows command prompt. Then you can do the
following
echo ATZ > COM1 # This resets the modem
echo ATM1 > COM1 # This turns on the modem speaker
echo ATL3 > COM1 # This sets teh modem speaker to high volume
echo ATDT > COM1 # This is the test. You should hear a dial
tone through the modem
echo ATH > COM1 # This is to hang up the modem
If you get a dial tone when you send the ATDT, you *have* a hardware modem
but if you don't, it doesn't necessarily mean that you have a winmodem.
