If I have a properly configured working modem installed, the first thing I
would do is to enter the following series of commands at the command line
while running in real DOS mode, (Not a Windows DOS-box):
echo ath0 > comx
where "x" is the comport number. The above command is entered to ensure
that the modem is on hook and hung up. Then enter
echo at&f > comx
where "x" is the comport number. The above command is entered to reset
the modem to its defaults. Then enter
echo ata > comx
where "x" is the comport number. If nothing happens, then you have a
winmodem. If you have a real modem you should hear a series of pitched
tones lasting for about 20 seconds and periodically interupted by clicking
sounds.
Another thing you can try is entering
echo atdt1234567 > comx
where "x" is the comport number. atdt is the dial prefix for touch tone
systems. For 1234567, substitute a real telephone number. If you have a
real modem you will hear the modem dialing the telephone number. Then you
should either hear the phone ring or you should hear a busy signal. If
nothing happens, then you have a winmodem. Winmodems are easily identified
by their unresponsiveness to DOS commands.
All the best,
Sam Heywood
P.S. Always remember: Do not answer the telephone unless it rings.
