We are trying to capture an RS-232 data stream using 
the serial port on a PC. The data appears at a fixed
rate and no flow-control is available. I don't want 
to make this harder than it has to be, but also don't
want to underestimate the job. Has anyone slain this 
dragon before? If so... any hard-learned lessons?

Specifically:
	1) Can I just do:

     OPEN(7,file=com1)
     READ(7,*) real1, real2, real3

	   or is there more to it than that?

	2) How fast (what baud rate) should I be able 
	   to read with a 5 Mhz XT (sorry, we're not
	   real big into DOS) before the fixed-rate
	   data overruns the machine?
		
Thanks in advance.

	Glen Clark
