I'm trying to set the baud rate for the modem port from MacPascal.  The
manual says that "A file variable opened with 'modem:' as the title
parameter reads from and writes to the modem at 300 baud."  No problem,
I say to myself, I'll use MacPascal's InLine facility to set 1200 baud
via the Serial Driver or the Device Manager.  That doesn't (read: I
wasn't able to get it to...) work because the Serial Driver and Device
Manager routines are OS traps, not Toolbox traps.  Apparently, InLine
only works for Toolbox traps.

Can anyone tell me how to set the modem's baud rate from inside MacPascal,
or (better) provide me with source code to do that, or (best) give me
MacPascal code that does some serious communications work (a dumb
terminal program, for example)?

Please mail your answers to me.  I'll post to the net when I find the
solution to this problem.

                               Thanks in advance.
