Dunno 'bout the raw DCE/DTE speed (ie., unaided by any AT command to the
contrary), but the M34F has this one command that certainly seems relevant
to the current discussion:

R    Host interface speed selection
       = 0*  Autobaud speed detection enabled
       = 2     2400bps
       = 4     4800bps
       = 7     7200bps
       = 9     9600bps
       = 12   12000bps
       = 14   14400bps
       = 16   16800bps
       = 19   19200bps
       = 21   21600bps
       = 24   24000bps
       = 26   26400bps
       = 28   28800bps
       = 38   38400bps
       = 57   57600bps
       = 76   76800bps
       = 96   96000bps
       = 115 115200bps

Since the "R" setting is saved as part of the various NVRAM
profiles, that means you can either save a locked DCE/DTE (host interface)
rate or have the modem always autobaud (which, as shown above by the
asterisk, is the default).

So?  :-)

This one can.

 BG> According to the Warp docs, NO version of OS/2 supports >57600 bps.

Are we 100% sure that it's COM.SYS and not MODE.COM that's enforcing this
limitation (not that it really matters with modem comms)?
