Serial Communication

[bc]

The -f option works ok if located directly after 'stty'.
In Windows ( not necessarily bragging here at all) I just set com1 to 
2400, 8, N, 1 with no flow control.
I just need to trouble shoot further and sort through the many serial 
options now.

Thanks for getting me started in the right direction though.
