[A83] Re: Link protocol help



Right.  I have used the CTS/RTS and DSR/DTR lines to communicate, and I know
my code works because I can **handshake** successfully with a TI calc.   I
need to use the MSComm control because it supports any Windows com port,
including "virtual" ports created by usb-to-serial adapters.  It seems that
the link libraries I have come across simply use hardware serial registers,
and this does not work with my laptop, which only has USB.  Maybe if I take
a look at the TILP source I will find some answers ... thanks!
