I seem to be having a problem with my Hayes Ultra 96 modem when trying to connect to another modem under certain conditions. It seems that if I have the &Q5 setting enabled and dial a modem with no error correction, the Ultra (or the other modem - a Hayes Smartmodem 2400) hangs up almost immediately after the connection. What could be the problem? -- Bob ______ Pro-Graphics BBS "It's better than a sharp stick in the eye!" ________ UUCP: crash!pro-graphics!bobl | Pro-Graphics: 908/469-0049 ARPA/DDN: pro-graphics!bobl@nosc.mil | America Online: Graphics3d Internet: bobl@pro-graphics.cts.com | CompuServe: RIP _________ ___________ Raven Enterprises 25 Raven Avenue Piscataway, NJ 08854

Well, it could be that you have S36 set to 0, or 4, which would cause it to disconnect if it were unable to establish an error-control protocol. Try that first. It could also be that the answering DTE doesn't tolerate very well the attempt to establish an error-control protocol, in which case the best solution (and what I _really_ recommend you do) is include &Q0 in your init string when calling a non-error-control modem. -- Toby Nixon, Principal Engineer | Voice +1-404-449-8791 Telex 151243420 Hayes Microcomputer Products Inc. | Fax +1-404-447-0178 CIS 70271,404 P.O.

Although I've never had any problems dialing into a _Hayes_ 2400 with my Ultra, I do with quite a few other brands. Instead of &Q0; however, I use &Q6, which lets me keep the DTE speed at 38400. I've never had even a Zoom modem fail to establish a good 2400 asynch connection with that setting. Just a bit less work than having to reset the comm port rate for each new asynch connection. -- Maurice INTERNET: lriggins@blackbird.afit.af.mil (129.92.1.2) Opinions expressed here do not reflect those of my employer nor constitute an official position of any U.S.Government agency.
