I've had pretty good luck with the same sort of approach. One aspect that hasn't been discussed much is the sex of the connectors. PCs have male DB-9s. The other type of gear usually has female (eg TBolt) so most of the time a straight-through M-F cable is all you need. They are also handy as extension cords. My null-modems are F-F DB-9s. I use cables rather than tiny gizmos. I think I have a few M-F null modem cables to handle the strange cases, but I consider them to be evil and try to keep them from getting mixed up with the good cables. (I know we had a handful of them at work because I botched the first try at a board. Sigh.) For totally evil, don't forget the cables used by APC UPS boxes. At least they are black rather than grey. I mark cables with || or X. -- These are my opinions, not necessarily my employer's.
