Terminal Settings to DEC VAX Computers
If you are using TELNET on the HP 1000 to connect to a remote DEC VAX host, you should set the communication protocol of the HP 1000 host terminal to XON/XOFF. The steps are as follows:
1.On the HP 1000, enter WH to display information about your terminal. Locate your session number.
2.Execute this command to set your terminal to XON/XOFF protocol:
CI> cn,$session,34b,1b
3.Use TELNET to log on to the remote DEC VAX host.
4.Once you are logged on to the DEC VAX host, execute this command:
$ set terminal/vt100. You can put this command in your LOGIN.COM file for automatic execution whenever you log on to the DEC VAX system.
5.Set your terminal to ANSI term type. See your terminal documentation for instructions.
6.When you have completed your TELNET session on the DEC VAX host and returned to the local HP 1000 host, reset your terminal to HP term type. See your terminal documentation for instructions.
7.Restore the local host to ENQ/ACK protocol by executing:
CI> cn,$session,34b,2b
Chained TELNET Sessions
Chaining makes it possible to hop across the network to different hosts.
If you chain several TELNET sessions, you may want to select a unique escape character for each host in the chain, using the ESCAPE command. Then you can escape to the node of your choice by issuing the appropriate escape character.
If all nodes use the same escape character, you can only escape to your local node; you cannot escape to an intermediate node.
If you chain TELNET sessions, the QUIT or EXIT command will terminate all sessions, close all connections, and return you to the local host. If, however, you log off the remote host, only the most recent TELNET session is closed. Any other chained sessions are still active.
If TELNET terminates abnormally or is aborted, any remote session chained from your session is automatically terminated.
Block mode applications over chained TELNET sessions are not supported.
Block Mode Considerations
The TELNET standard specifies a character mode protocol. Character mode is the normal operation of a terminal.
With block mode, data is not transmitted one character at a time. Instead, an entire block of data is typed in locally on the terminal. When the enter key is pressed, the data is transmitted from the terminal to the computer.
