I recall from 2nd quarter 1991 a Motorola System-V/68K system that
included a utility `porthold(8)' (or some other name found through
`man -k port | grep hold') for the very purpose of making tty settings
sticky.  It read a file (whose default name I can't recall) of device
names and initial settings and then slept holding them open.  It may
even have reread the file on SIGHUP.  Perhaps someone would be interested
in tracing the manual page and reverse engineering it :-)
