  If he's planning on using ST basic, (but this should work in other
dialects) use this statement:
OPEN "O",filenumber,"AUX:"
where the "O" represents Output file, filenumber is an integer number used
to identify the file. If he plans on inputting data, use "I" instead.

Another way to do this in ST basic is to use the INP and OUT statements.
OUT 1,N% will output a byte (if 0<=N%<=255) to the RS-232 port. To read the
port use
IREADY%=INP(-1) 
if the value is .not. zero there is a byte available and then use 
IDATA%=INP(1)
to get the byte. if you do not use the IREADY%
check, THE SYSTEM WILL HANG until there is a byte available. (This disables
any keyboard [Ctrl-C] or AES events)
