Hi. Anyone have a source for reliable V23 modems that fake the 75 baud back channel to 1200 baud so they can be used on a computer that doesn't like split-speed action? Southwestern Bell has flooded Houston with cheesy Minitel terminals and I'd like to make a BBS accessible to them. -- Peter da Silva. `-_-' +1 713 274 5180. 'U` peter@ferranti.com

When I was inquiring into v.23 modems to see what would be involved in supporting users in the UK, I was assured that the v.23 modems sold for home use there *all* fake the back channel to 1200 baud. This seems like the right way to do it.... I just don't know where you're going to find one for sale on this side of the Atlantic. Dave

This seems like >the right way to do it.... Sorry, but there do exist many V.23 modems which require the DTE interface to talk to the back channel at 75 baud. One clever chap here in New Zealand managed to write a comms package which fakes 75 bps on an IBM PC by toggling lines directly (since the clock chip doesn't have a divisor to do this). So, it *is* possible to use a 75 bps channel on a PC, if you've got the right software. It's mostly the cheaper V.23 modems which fail to lock the DTE speed to 1200 bps. -- Paul Gillingwater, paul@actrix.co.nz
