For low baud rates, this should be easy. I've never tried this, but:
Install the com/dvr driver from DOS (set *cl com/dvr), and set up the
port with setcom. Then, in basic, do something like:
open"i",1,"*cl"
open"o",2,"*cl"
Then use input#, line input#, or input$() on file 1 to read the rs232 port
and use print# or write# on file 2 to write to the rs232 port.
See manual on basic file io; it's been years.
