As far as I can tell, it must have been this:

revision 1.99
date: 1997/04/04 20:56:34;  author: mycroft;  state: Exp;  lines: +890 -751
New version of com driver.  Uses a different queueing mechanism and a split
hardware/software interrupt mechanism for improved performance.  Many odd
protocols bugs also fixed.

I can't tell if TIOCMGET/SET/BIS/BIC was in the way of correct handshaking
protocols, or simply not (yet) implemented.
