Further to Soenke's excellent reply, Modem Manager is brilliant!
(Thanks, Jawaid!)

The default GS/OS modem port driver is generated automatically by
GS/OS.  It knows nothing about extended control calls.  The only way
to change the baud rate, etc. would be to send commands through the
serial firmware (e.g. "Control-A nnn B" to set the baud rate).  I
haven't tried this, and have no idea if it will work.

The only way to access the serial firmware's extended calls is through
the FWEntry toolbox routine.
