Reading ALDL 8192 stream from '165

[Pat Ford]

Hi there:
 Looks like you're using basic, I haven't used basic in a while BUT
isn't the syntax for open open "port,baud,parity,bits,stop bit"?
if so try something like OPEN "com1,8220,n,8,n". As I recall there
is no stop bit, no parity, 8bits, as I mentione earlier I may
not remember the syntax of open.

good luck

ps if I got anything wrong let me know
