You may wind up having to put something into your autoexec.bat file to send this string to the modem each time that you re-boot. In some cases you can get by with a mode command followed by copying a file containing the aforementioned string (note that '\r' is control-M) and sometimes you can't. Experimenting is the only way to find out. Also note that the timing of sending characters is sometimes important (ie send them slowly), but other times it isn't. In short, good luck.

I am having the same problem with my Hayes 1200b internal modem. I hooked up a toggle switch so that I could either use the modem or talk on the phone. This problem first appeared after a lightning storm. I assume a switch was blown inside the modem. Does anyone have a suggestion for fixing this problem? Dave Boyer

I tried searching backwards on the subject line, and if I did post the article has expired here. Therefore, my apologies if you've seen this before. I don't know why your modems are behaving as they are. Some modems have default settings in non-volatile memory, and it is possible that the freek occurances that have been mentioned have corrupted that memory. Check your modem's documentation to see if this might be the case. If so, you should be able to configure the modem using AT commands and save the configuration in memory. As for a quick fix, you can disable auto-answer by setting the value in register S0 to 0. Putting the line "echo ATS0=0 > COMn" (minus the quotes), where n is the COM port to which your modem is assigned, in your autoexec.bat file should do the trick.

You may wind up I have a real Hayes Smartmodem 2400 and it *DOES* come with non- volatile memory.... Since when the existence of such memory VERY NON-STANDARD? I assume that the Hayes 2400 is a fairly good example of a "standard" modem... After all, Hayes did invent the protocol commonly used in all "hayes compatible" modems.. Most Hayes compatible 2400 baud modems come with standard non- volatile memory... You might have been thinking of the older 1200 baud modems that use to have switches.... Is this what you were implying? If so, then what you stated is true.... It's sort of confusing when two levels of replys are imbedded in the message.... George

If the modem is a Hayes compatible, the AT command set can turn off the modem's "Auto-Answer" feature. The command is: ATS0=0 This command should turn off the Auto-Answer feature.

Some software communcations packages allow for autoanswer disable/enable that can be stored in nonvolitile ram or registers on your modem... Are they Hayes or Hayes compatables? Try setting S0=0 and using the &W command to save the configuration change. If the modems came with documentation, they must have something about this problem in them. -- Colin Sachs - csachs@oucsace.cs.ohiou.edu "I believe in everything; nothing is sacred.

If you have Kermit, an AutoExec.Bat line of Kermit Hang will load Kermit, lower DTR, and exit, which should stop your modem from auto-answer. Or, you could use a shorter program to lower DTR, but I think the load time of Kermit is better than wasted disk space. This assumes that your modem cable includes DTR (pin 20 at the modem), and that the modem is set to follow DTR. In Microsoft C, for Comm 1: main() { outp ( 0x3FC, 0x00 ); /* 00 to turn off DTR, 01 to assert it */ return(0); } -- --- Clarence A Dold - dold@tsmiti.Convergent.COM (408) 434-5293 ...pyramid!ctnews!tsmiti!dold P.O.Box 6685, San Jose, CA 95150-6685 MS#10-007
