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. ================================================ Kent West, Technology Support [EMAIL PROTECTED] Abilene Christian Univ., Abilene, TX 915-674-2557 FAX: 915.674.6724 Amateur Radio: KC5ENO Debian Linux: Ride the wave with the penguins!
