Appendix A

Async Terminal Operations

Before establishing an end-to-end link, an async terminal must make a connection to
the async PAD, as follows:

1. Once the SmartSwitch 1800, async terminal, and any modems in the link are

powered on, do this at the terminal:

If a specific line speed is configured in the Port record, go to step 2.

If the async PAD port is configured (in the Port record) for autobaud and
parity auto-detect, press

[Enter]

, then

[.]

, then

[Enter]

.

If the port is configured for autobaud only, press

[Enter]

.

Data bits and parity settings must match throughout an
async connection.

2. If the port is configured (in the Port record) to not require login, go to step 3. If

login is required, enter (when prompted) the login password defined in the

Async

PAD Login record

(described on page 12-7).

3. The

Async PAD banner

(described on page A-5) will be displayed at the top of

the terminal screen. The terminal is now in

Command

mode, described in the next

paragraph.

Command and Data Transfer Modes

The async terminal has two modes of operation. Local operations at the async terminal
are performed in

Command

mode. In

Data Transfer

mode, the PAD interprets all input

from the terminal as data, and transmits it to the remote device.

If this is a PVC connection, you can enter

Data Transfer

mode from

Command

mode

by entering the PAD recall character specified in the Async PAD profile. If this is an
SVC connection, you must send a Call Request packet to enter

Data Transfer

mode.

(See “

Placing a Call from an Async Terminal

” on page A-2.) Either way, once in

Data

Transfer

mode, you can toggle back and forth between the two modes by entering the

PAD recall character.
