Sorry to bring you down, but it won't work without some quite
complicated and expensive external electronics. The TI has no serial
port and the link port can't be used as one. You need an UART or a
microcontroller in between. This is mainly due to the fact that the TI
lacks an accurate (crystal) clock. (Except the 92 maybe...)

[Jan Zumwalt]  I don't know anything about the TI hardware, that's why
I'm here :-) but... is the link port able to be set up as a interrupt?
