Recently I was playing with some of the new GEOS software for the C=64, and
lo and behold I found that the program GeoLaser uses a 9600 baud speed!

After talking to a good friend of mine about it, and confering with another
friend with connections at BSW (the published of GEOS), we have figured out 
that the programmer of the geoLaser program needed a way to send data to 
an Apple LaserWrite (POstScript) at 9600 baud.   Solution?

Seeing as how the C=64 (and 128) don't contain UART chips, and do all of
the RS232 type operations via software, he just wrote his own rs232 
driver program.  It blanks the screen, but it works...  Might try to extract
it at sometime...  If I can I'll post something else here 'bout it...
