4. You must issue certain commands to the Print Server Plus
to establish a virtual connection with a network modem. You
may send the necessary commands from a DOS prompt
(Step 4a), from within your network communications
software (Step 4b), or by using the DIAL program (Step 4c).
4a. DOS Method: The DOS method to open a virtual
connection utilizes the MOPEN command which has the
following syntax: MOPEN <print server name> <n> <t>
where <print server name> is the name given to the Print
Server Plus using PSQMGR and <n> is the port number the
modem is connected to on the Print Server Plus (0 to 3).
There should be a single space between MOPEN and <print
server name>, a space between <print server name> and
<n>, and a space between <n> and <t> (if used).
WARNING: Do not use the exclamation point symbol (!) as
part of the print server name which is configured using
PSQMGR if you intend on using the MOPEN statement to
establish a connection with a network modem.
The optional parameter <t> causes MOPEN to enter into a
terminal mode after establishing the connection. This allows
a user to communicate with the modem without having to
execute a communications package. Anything typed on
your keyboard will be sent to the modem and any data
received by the modem will appear on your terminal screen.
Type <ESC> to terminate this mode.
If a virtual connection is established with a modem port
using the MOPEN terminal mode, you may instruct the port
to go into a loopback mode where the selected port's UART
will loop back all characters typed by the workstation.
Loopback mode is useful in troubleshooting communication
problems with the attached modem. If characters are
looped back by the selected port, this indicates the port is
functioning at the UART level.
