Serial/Null Modem notes

A very interesting list of notes about serial connections. This reminded me of the Lantronix issue I dealt with a few months back in which the Lantronix would literally begin to crawl when hooked up to a Nortel (I think it was a Nortel) phone switch: Plug in the phone switch, Lantronix crawls; remove phone switch, Lantronix returns to normal. Literally NO setting I could put in place would correct this. This link gave me some new ideas that didn't pop up at the time.

Slight edit: This link shows a nice option for making null modem adapters with RJ45-to-DB9 adapters. I really want to try this out now.
