How about one Z8530? :-) [it's a DUART, for the Zilog-impaired]
The "problem" with picking something like a SYM-1 is that it lacks a
suitable output device. A few digits just isn't all that useful when
picking through a stream of serial data. I would have to say with my
HP experiences, that a Commodore SX-64 is about entry-level for that,
just because it's portable, has an expansion port for the serial chip,
and has a built-in 40-col screen. That having been said, a real HP
isn't much more expensive than what the SX-64s go for, and it's 1/2
the size and weight, and is already set up to do the job.
In principle, I don't see a problem with trying to roll your own line
analyzer, but having written a lot of code that bangs on Z8530s and
8250/16550s, I'm really happy that I have a working, ready-to-use
bench tool to watch the serial stream for me. For what an HP eBays
for, I can be up and snooping a whole lot faster... a time/money
tradeoff that _I_ would load the money side of the equation for.
