RE: TI-H: Okay I maybe overreacted



Could/would someone please tell me what transpires during a 
link. I would be interested in any information from generic to 
expert. Of special interest would be if it uses a proprietary 
protocol, bit rate (baud), how handshaking is accomplished, etc. 
Has anyone with a digital scope looked at it (I have only 
analog).

Wow! I just thought of something after that last request. It 
should be simple to log the data because (no brainier) you are 
hooked to the parallel port. What I need then is to know what 
the protocol expects for handshaking. Then I could write a quick 
program to log the data. What puts the link into rx/Tx mode, 
etc.

Thanks
