I disagree. Terminal programs should give you the "option" of opening the
serial device in SHARED mode. A-Talk III allows you to do that by using
the SHARED keyword either on the CLI command line or in a Tooltype.

Quite true. The comm program must give you a 'menu' selection that
aborts all active requests and optionally saves the current serial
device status.  A-Talk III does that too.  Of course, none of these 
problems are present when using and XPR-based protocol library.
