I called Telebit tech support this morning. A tech support staff person called back a few minutes ago and we spent some time verifying that the Toshiba laptop internal 2400 modem does indeed fail to connect with a T2500 at 2400 baud. The only way we could get a connect was to force the T2500 to stay at 2400bps (S50=3, S51=2). If the T2500 is set to autobaud, no connect. Again, this seems to be unique to the internal 2400 modems from Toshiba and Everex. External 2400 and 1200bps modems seem to work fine with the T2500. Telebit is looking into this...todd -- Todd Ogasawara, U. of Hawaii UUCP: {uunet,ucbvax,dcdwest}!ucsd!nosc!uhccux!todd ARPA: uhccux!todd@nosc.MIL BITNET: todd@uhccux INTERNET: todd@uhccux.UHCC.HAWAII.EDU
