D.4 Dealing with a COM1 Port Jam
Occasionally, when the COM1 is under software flow control, as it is
when you use a terminal emulator to communicate through it, COM1
can jam. If this occurs, your emulator will have no control of the
system or partition to which it is attached. You can clear the jam by
clearing the communications link in the emulator and using the SCM
clear port command to un-jam COM1.
