I would actually disagree. I have systems with multiport serial cards installed, and I much prefer those to be named differently. Not only do I not have to worry about the same problem I *constantly* have with onboard Ethernet cards -- whoops I just installed an expansion card and suddenly my onboard NIC is eth2! -- but the expansion serial ports tend to be *different.*
For example, on my serial server, the Cyclades ports (ttyC*) use RJ-45 connections from an external expansion module, whereas of course the builtin ones (ttyS*) use DB-9s.
