CHAPTER 7: UNIX/RTEL Host Setup
In addition, verify that the service is available. Issue the server command SHOW SERVICE serv_name CHARACTERISTICS. The service port should be the port the printer is physically connected to and the service rating should be
If the service rating is zero, the service is not available. Verify that the port is set to access remote or dynamic (see the server commands define port n access remote or define port n access dynamic).
Log the port out using the command LOGOUT PORT n. This will force the server to
7.Verify that the port characteristics (baud rate, parity, flow control) match the settings needed for the printer. Remember that these characteristics need to be both SET and DEFINEd.
8.On the server, use the MONITOR QUEUE command to see if the UNIX host is attempting to make a connection. When a job is active, the a queue entry from the UNIX host to the specified service should appear.
9.As a last resort, connect a terminal to port n and see if data is appearing on the terminal when the EPS attempts a print job. You should also try connecting to the service locally to verify the ETS’ setup is correct.
If the printer still does not function properly after verifying these conditions, contact Technical Support.
7.11 Connecting to a Specific Port Using Telnet
You can connect to a specific port on the EPS by using the Telnet command with the “port number” parameter. For example, to connect to serial port 3 on the EPS, first make sure the port is set to ACCESS REMOTE or ACCESS DYNAMIC, then issue the command:
% telnet server_name 2003
The number 2003 is the EPS’ base port address 2000 plus the actual port number 3. For more information about the TELNET command, refer to your host’s documentation for TELNET. Note also that “raw” TCP connections (no Telnet character interpretation) are available by using the ports starting at 3001. Connecting in this manner attaches the telnet session directly to the port, allowing access to the modem, printer, or terminal device attached to that port. The EPS will not echo characters unless the device attached to the serial port echoes data.
