Hello,

     The problem I'm having is with the "TI-Graph Link".  I realize that it 
is possible to impliment full-duplex asynchronous communication with extra 
hardware.  But I'm wondering if there is a way around this problem that 
doesn't involve ditching the current TI-Graph Link, or modifying the host 
software any.  I don't want to have to use an alternative graphlink.

talk to you later,

David E. West
