Failure of the modem to react to an AT command can be cause by an interrupt conflict. I'm not completely up on IRQ settings but the IRQ 0 you show above is one I've never seen used with a modem. Ordinarily it has been used by the system timer so you might consider configuring the modem to use another one. Common IRQs for a modem are 3, 4, 5 and 7. (You might have to disconnect IRQ 7 from the printer in your BIOS setup program but it's not really needed for common PC printers.) |You can see that i receive 1 time the OK-string and then it's end and |time-outed. Can't explain why the first worked and the second didn't but there's not many posts with this symptom for an IRQ conflict - if that is causing your problem. --- Clifford Kite Not a guru.
