This is the one, Peter; sorry I didn't give you credit.

In all fairness, the code is almost entirely Mr. Honeyman's, with only
minor changes by Mr. Theisen (to better support PC serial cards, as I
recall).  I also added in my own changes, because a floating
carrier-detect line on an attached terminal was causing serial I/O to
hang on the port.*

Anyhow, I certainly sould have mentioned Peter Honeyman, because even
though his name isn't at the top of the RCS changelogs anymore, it
certainly appears next to most of the changes!

*This involved a slight hack to only check the status of the carrier
detect line when an MSR interrupt was received.
