I think I didn't explain myself properly in my earlier posting. Either that or I've misunderstood your response. What I would like to see is a mode where (for example) the modem detects 2400 bps / MNP4, and talks to the host computer at 4800 bps. If 300 bps (poor sods) with no protocol was used, it would talk to the host at 600 bps. That is, don't have the host<->modem interface fixed, but let the link take advantage of the protocol's extra throughput. For dialin applications the verbose message returned to the host is not really important. What IS important is the data rate used by the modem. Any decent getty (or appropriate substitute) can handle it from there. For dialout, the same scheme would be used, but the CONNECT message is used by the dialler to switch line speed. Do you know of any modems that will do this? _____________________________________________________________________________ David Burren [Athos] Work: david@bacchus.esa.oz.au Software Development Engineer +61 3 819 4554 Expert Solutions Australia Home: athos%eyrie@labtam.oz.au Hawthorn, VIC +61 3 509 5775 - eyrie: Home of the Ninja Wookie -
