Serial port (/dev/ttySX) question.

[Gene Heskett]

Greetings all;

rs-232 tech is getting old, like me.

Do we have a tool that can display graphically in near real time, the status 
of the commonly used wires/signals in the '7 wire' protocol?

I need something that works a bit like the old db25 tester with a bunch of 
LED's to tally the line states like that gismo Radio Shack sold 20 years ago.
Those blinking leds were a very good troubleshooting tool, and I'm having 
flow control problems that look like a system freeze on one end or the other, 
but when rz times out, I still get a prompt from the shell on the other end, 
but nothing I type here arrives there, like hardware flow is still in effect 
and turned off on one end or the other.

Thanks All for any hints.

Cheers, Gene
