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. -ethan
