Just one thing: If you set S92=1, sites that call you and expect to connect in PEP mode will have to set their S50=255 (to force a PEP connection) before doing the dial. Normally S50=0 (auto-speed determination). If the calling TB modem is set S50=0, and the answering TB modem is set S92=1, they happily sync up at whatever speed the answerer sends tones for first -- typically 2400, the way mine are set up. Having the caller do S50=255 solves this; the calling modem patiently waits until the PEP tones show up (assuming you both set S7 large enough; I set mine to 90 seconds). --- Jamie Hanrahan, Simpact Associates, San Diego CA Chair, VMSnet [DECUS uucp] and Internals Working Groups, DECUS VAX Systems SIG Internet: jeh@dcs.simpact.com, or if that fails, jeh@crash.cts.com Uucp: ...{crash,scubed,decwrl}!simpact!jeh
