USING TSO VIA ARPA NETWORK VIRTUAL TERMINAL

A. Connecting to TSO

-----------------

IBM's Time Sharing Option (TSO) is available at UCLA-CCN on Socket 1

using the standard Telnet protocol.

1. To access TSO, the remote user performs ICP to Socket 1 at CCN

and executes the command:

TSO CR LF

-- --

2. Possible responses to the TSO command are:

a. "WELCOME TO UCLA/CCN TSO"

followed by a herald ("!"). TSO is available. A TSO LOGON

command should be entered following the herald.

b. "TSO NOT AVAILABLE AT THIS TIME"

The user should check the TSO schedule and verify that it

should be available. If so, he can call the CCN on-line help

phone, 213-825-1652 for availability information, or send a

message to the operator through NETRJS.

c. "ALL TSO PORTS BUSY"

The user should try again after a short time. If this

condition recurs frequently, notify the Technical Liaison at

CCN so that more Network ports can be added.

3. When first connected to CCN server Telnet, the user has a choice

of several commands besides "TSO". The TSO-related commands are:

HELP - A listing of commands at this level, and other

general information.

BBOARD - List operational notices.

4. Local echoing (i.e., by the user site) is required.

5. Server-Telnet will time-out and disconnect the user if:

a. Output to the Network does not complete within 5 minutes, or

b. An INS, DATA MARK pair does not match within 2 minutes, or

c. TSO waits for the user to enter input for 20 minutes.

B. Conversing with TSO

-------------------

1. TSO is strictly a line-at-a-time system. Input is not scanned

until either an end-of-line or an INS (interrupt) is received at

CCN. TSO sends the user an exclamation mark ("!") as a herald

when waiting for input.

2. The end-of-line indication for input and output lines is the

standard CR LF sequence.

3. The remote user my interrupt TSO output by sending an INS and

DATA MARK (Telnet X'80'). Note to TIP users: this may be

accomplished with the TIP command "SEND SYNC". Each such

interrupt is passed to...
