Name
Purpose Assigns a unique name to each port.
Applies To All port types.
Possible Values Each name can be up to 8 characters in length. The
first character cannot be a number. You can use any
ASCII keyboard character in the name except
comma (“,”), asterisk (“*”), slash (“/”), question
mark (“?”), carriage return (“Enter”), escape (“ESC”),
and “at sign” (“@”, the command-start character).
Usage Notes By default, ports 4, 8, and 12 are assigned the names
PRINTERA, PRINTERB, and PRINTERC; the other
ports are named P01 through P11. You can change
any of these. You might want to assign names based on
whether a user or peripheral is connected (for
instance, USER1 or PLOTTER2). It is advisable to
group similar peripherals with similar names to allow
easy selection with wild-card characters, if required.
For example, you can select the first available of
MODEM_A or MODEM_B with MODEM_?. No
name can be used more than once.
Type
Purpose Determines the direction of data through each port.

By default, ports 4, 8, and 12, whether serial or
parallel, are defined as
output ports; all other parallel
ports are defined as input ports; and all other serial
ports are defined as
bidirectional
ports.
