Thanks for everyone's suggestions for my question about PC-based
oscilloscopes for debugging PICs. I had no idea there were so many
options out there.

If I may, I'd like to ask my question again with better clarity:

I'd like a device that could:

- Interface to PC via serial or parallel port
- Monitor up to 8 lines at a time - like a Trace, I guess
- Have high enough resolution to be useful debugging 9600 RS-232 (TTL
levels)
- Have really good Windows-based software

Does anyone know if such a thing exists?
