Setting Up and Managing TELNETSYM

The TELNET print symbiont (TELNETSYM) provides remote printing services

that enable the use of standard OpenVMS printing features not available with

the LPR/LPD print service. With TELNETSYM conﬁgured on your system, you

can set up and manage a remote printer attached to a remote terminal server as

if it were directly connected to your system. The TELNET symbiont functions in

a manner that is similar to that of LATSYM for Compaq’s local area transport

(LAT) software.

The TELNET symbiont performs the following functions:

• Transfers record-oriented data to printers.

• Conﬁgures printers attached to terminal servers that support TELNET.

• Supports outbound print jobs and offers standard OpenVMS preformatting

for outbound print jobs.

This chapter reviews key TELNETSYM concepts and describes:

• How to start up and shut down the TELNETSYM print service (Section 23.2)

• How to set up a TELNETSYM print queue (Section 23.3)

• How to set up a relay queue (Section 23.4)

• How to managing and customize TELNETSYM print queues (Section 23.5)

• How to solve TELNETSYM problems (Section 23.6)

23.1 Key Concepts

TELNETSYM is a true OpenVMS print symbiont; it performs all print formatting

functions, such as header and trailer page generation, pagination, queuing, and

handling of multiple forms. TELNETSYM extends the OpenVMS print symbiont

by redirecting its output to a network (TELNET) channel.

TELNETSYM sets its process names to TCPIP$TNSYM1, TCPIP$TNSYM2,

and so on. Each TELNETSYM process can control up to 16 print queues.

You can control the maximum number of print queues by deﬁning the

TCPIP$TELNETSYM_STREAMS logical, as described in Section 23.5.6.

23.1.1 TELNETSYM Modiﬁcations to the Output Stream

TELNETSYM adds escape (0xFF) bytes in the data stream so they are not

mistakenly interpreted as TELNET protocol IAC commands.

TELNETSYM doubles any TELNET IAC characters found in the byte stream

unless TCPIP$TELNETSYM_RAW_TCP is deﬁned for the queue. The IAC

character is a hexadecimal FF.
