When I was writing code that used the serial driver I found a utility that
forced a close of the serial port (since my code did not always word!). A
search on CompuServe's Mac forums found something named CommCloser by Ron
Grunwald from 1995. The file is 11kb in size and I've sent it directly to
Mark. I don't know if attaching will work, however, since my daytime machine
is Wintel.
