How to set up Telnet printer on DECserver?

» close window

The Question is:

 
We are switching from bridged LAT to routed
TCP/IP. Our application assigns printers
to terminals using LAT devices. Now with
terminals connected via DECserver 700 to the
cluster, there are no more static identifiers
for the terminals and therefore we are unable
to build printer terminal relationships.
 
Is there a way to assign a terminalserver port
a static and unique identification, prefferably
a (pseudo)-LAT device?  We are using UCX
version 3.3
 
 

The Answer is :

 
  Please see the previous "telnet printing to HP printers?" and
  "LAT-telnet gateway?" discussions.
 
  On most DECservers, you can define a telnet listener port and point
  it to the DECserver port where the printer is connected:
 
    Local> DEFINE TELNET LISTENER <port_number> PORT <port_number> ENABLED
 
  For example:
 
    Local> DEFINE TELNET LIST 2002 PORT 2 ENABLED
    Local> SHOW TELNET LIST 2002
 
    Listener TCP-port:  2002
    Identification:
    Ports:              2
    Connections:        Enabled
 
 
  With any printer-specific or site-specific adjustments necessary, set
  up the DECserver printer port as follows:
 
    Local> SHOW PORT 2
 
    Port  2:                               Server: LLANO
 
    Character Size:            8           Input Speed:               9600
    Flow Control:            XON           Output Speed:              9600
    Parity:                 None           Signal Control:        Disabled
    Stop Bits:           Dynamic
 
    Access:               Remote           Local Switch:              None
    Backwards Switch:       None           Name:                     PCM02
    Break:                Remote           Session Limit:                4
    Forwards Switch:        None           Type:                      Ansi
    Default Protocol:     Telnet           Default Menu:              None
 
    Preferred Service: None
 
    Authorized Groups:  63
    (Current)  Groups:  63
 
    Enabled Characteristics:

    Output Flow Control,  Verification
 
 
  The command used to set up the Telnet print queue is:
 
    $ INIT/QUE/PROCESS=TELNETSYM/START/ON="server_ip_nodename:port_number"
 
  For example, the command to initialize and start the queue "TCP_PRINTER"
  to send output to a printer connected to a DECserver 300 with an IP node
  name of TCPSERVER that is listening on port 2007 would be:
 
    $ INIT/QUE/PROCESS=TELNETSYM/START/ON="TCPSERVER:2007" TCP_PRINTER
 
 
  If you are having problems with timeouts, you might want to try to
  increase the telnet symbiont's idle timer:
 
    $ DEFINE/SYSTEM UCX$TELNETSYM_IDLE_TIMEOUT "0 00:02:00.00"
 
 
  In addition to the information in the Ask The Wizards topics mentioned
  above, to test the printer, if the terminal server's name is FOO and the
  printer's physical port corresponds to TCP port number 2005, you can
  connect to it by typing:
 
    $ TELNET FOO 2005
 
  Telnet symbiont diagnostics can be enabled with the logical name:
 
        DEFINE/SYSTEM UCX$TELNETSYM_VERBOSE 1
 
  The log file is UCX$LPD_SPOOL:UCX$TELNETSYM.LOG
