Help: I am using a T2500, and have to use V23 to access British Telecoms 'Phonebase` - on-line white pages. Can the T2500 do the baud rate splitting internally, as I cannot have a split baud RS232 port. I tried ATS50=5, but this just gives me an ERROR. Any help greatly appreciated. Wouldn't you expect BT, the monoploy phone company in the UK (the other fish do not count - yet) can't put anything but V23 up ?

The U.K. modem uses an RS232 speed of 1200 in both directions, while the modem transmits at 75 bps and receives at 1200 bps. No need for a special port in your computer... >Peter Galbavy E-Mail: P.Galbavy@micromuse.co.uk -- .------------------------------------------------------------------------. | Greg Andrews | UUCP: {apple,amdahl,claris}!netcom!gandrews | | | Internet: gandrews@netcom.COM | `------------------------------------------------------------------------'

Living in Canada and dealing almost exclusively with North American modems, I've never had the fun of using one of these... do V.23 modems in general use handshaking to prevent modem buffer overrun, or do the manufacturers simply hope that no one will try an ASCII upload or streaming protocol transmit over these devices? -- Geoffrey Welsh - Operator, Izot's Swamp BBS (FidoNet 1:221/171) root@zswamp.uucp or ..uunet!watmath!xenitec!zswamp!root 602-66 Mooregate Crescent, Kitchener, ON, N2M 5E6 Canada (519)741-9553 "He who claims to know everything can't possibly know much" -me
