It's possible, but it depends on the modem.  Let's presume that your modem
can be set via software.  The way I normally do this is not to change an
existing line/ctl/dev, but to create a new one on the same I/O resource.
Vary off LINE4800 and vary on LINE9600.  You can then adjust the new
settings without fear of breaking the existing ones.  When done with
LINE9600, vary it off and vary LINE4800 on.

One fairly painless way to do that is to write a little CL program that
varies off all line/ctl/devd's on a resource and then varies on the one you
pass in as a parameter.  Call this VARYCL from each of your comms programs
and you'll be sure that the right description will be varied on.  Next
month, when somebody says "I need to dial X company at 2400bps" you can add
a few lines to the CL program and never worry about your existing comms.
