Hmmm. I don't know what to say. Is your modem on /dev/ttyS0, or another
port? If it's on /dev/ttyS1, of course you'd need to make the appropriate
change in the command. Other than that, I don't know why it wouldn't work
(but then I'm certainly no expert).
Oh, one other possibility that comes to mind. If your serial ports are set
too fast for you modem, you might not get a response. For example, if your
serial ports are set at 115,200 and your modem is only a 14,400, the modem
might not respond. I had this problem with a 2400 modem. Nearly drove me
mad, because I KNEW the modem worked.
