I would appreciate your opinion / suggestion, on what is going on with my modem. It worked fine until two days ago. It does not respond to my commands but appear to execute them. In other words: at does not result in an ok atdt ####### dials the number given This fouls up all my kermit scripts and forces me to lift the receiver to make sure that the call is answered (you are right, this is not a big deal but.....). I am embarrassed to admit that I do not know the make of the modem, the manual refers to it as Super Modem 2400, and it is an internal one. Any and all guidance will be greatly appreciated.

According to a generic "Hayes" modem manual which I have, ATQ1 disables result codes, while ATQ0 enables result codes. Some modems also have a switch to set the power-up default state. Hope this helps. Bruce Miller (miller@gvlv3.gvl.unisys.com) <Insert virus code here> Vacuum tubes are not dead - they just smell that way.

Possibly the result codes have been turned off by the 'Q' command. Try "ATQ0" to make sure they are enabled. On Hayes compatible modems you can also select whether you get english or numeric codes. "ATV0" enables numeric codes, "ATV1" enables english codes.

The most common reason a modem will appear to "work" (meaning it can respond to commands from the PC) and still not yield information to the PC is the IRQ line for the modem is not responding. And the reasons for that are missetting of jumpers to other than 4 or 3, other things sitting on the same IRQ and active at the same time, other. What this means is the port address is ok so the modem gets commands from the PC but the modem's responses generate no usable interrupts to dump characters into the comms program. Still one more case is the modem is not even close to being like the standard 8250 UART. MS-DOS Kermit responds by using the Bios and the Bios may not provide any responses until DSR and CTS are asserted by the modem. Joe D.
