GM serial line communications

[wmcgonegal at rr.etc.ncr.doe.ca]

At the end of January there was some interest in reading the 8000 baud GM serial
data line.  I mentioned at the time that we had done this at our lab using an PC
serial port.  There is some minor circuitry involved in the interface to invert 
the signals.  You also need to set up the serial port for this nonstandard baud 
rate.  I wrote a program to set up a nonstandard baud rate.  I am helping 
someone set up this communication link and I know there were others interested. 
If anybody else one wants a copy of the program to set up the correct baud rate 
or some of the source code I can forward the information to them.  Perhaps there
is a place that I can post this in the DIY EFI archives.
