3.23 PRINTER ATTACH/DETACH
PA [<port>]
NOPA [<port>]
PA attach a printer to a specified port. NOPA detaches a printer from a specified port. When the
printer is attached, everything appearing on the computer terminal is echoed to the attached
printer. If no port is specified when executing PA, the default is port 1. NOPA detaches all
attached printers. The port number must be in the range 0 to $1F.
If the port number specified is not currently assigned, PA displays an error message. If NOPA is
attempted on a printer that is not currently attached, an error message is displayed. Use the PF
(port format) command to configure the port before attaching a printer to it.
RECOVERING FROM A ''HUNG''PRINTER: attached ports are not detached by exceptions
(bus errors, abort, etc). If PA is executed using incorrect parameters, or a fault such as a paper
jam occurs, press the RESET switch on the M68300PFB Platform Board to recover control of the
printer.
