IIRC, the syntax was similar to:
100 open "COM1:" for output as #1
Then just use input # and print # statements for I/O.
In MS Basic 1.0 for Macintosh there was no way to set the
baud rate without peeking and poking at the 8530 SCC chip
registers. (Somewhere in storage I may have a notebook
with the addresses of those registers...)
Not sure about MSB 2.0... perhaps try something like:
110 OPEN "COM1:2400,N,8,2" FOR OUTPUT AS #1
120 OPEN "COM1:2400,N,8,2" FOR INPUT AS #2
This is also similar to the serial ****t open syntax I used
for Chipmunk Basic:

IMHO. YMMV.
