US Robotics 56K Voice Faxmodem

Interesting stuff - you are using both hardware and software flow control.
(I RTFMed along time before mailing the group! :-))

I'm not actually getting numeric codes out, that was set by the ATV flag,
which is set to 1 - what is coming out is truncated output for the OK, and I
don't always get that much either.

Other than flow control - which I've tried changing the two differences
remaining are that your modem is external (which seems like a bloody good
idea right now) the speed at which your modem is running is lower. Is this
speed set by the terminal - does anyone know? There is no reference to it in
the manual for the modem. FreeBSD manual suggests that this is negotiated by
the modem at startup. I'm running a 16550A UART, which I thought should
handle this speed. Oh well...

I'm beginning to think that this has a lot less to do with the modem than
the configuration of the serial ports and devices.

Thanks for the help guys - if there are more ideas out there, lets have 'em!

Cheers,

Jon
