Echo; Keyboard Dialing; At Dialing; Extended At Command Dialing - Nortel Meridian SL-100 Reference Manual

Echo

During call set-up, all user inputs are echoed by the MCA to the terminal. To
turn the echo off (command state), enter the command E0 (zero).

Keyboard dialing

With keyboard dialing (KBD), the user can originate data calls to local and
remote hosts or DTE by using the terminal keyboard. KBD is only
supported for ASCII, asynchronous, character mode, interactive terminals
equipped with an EIA RS-232-C interface.
Note: KBD does not support block mode terminals.

AT dialing

AT dialing refers to the capability of originating data calls to local and
remote hosts or DTE using a terminal keyboard or personal computer. The
AT dialing feature supports only ASCII, asynchronous, character mode,
interactive terminals equipped with EIA RS-232-C interface. AT dialing is a
part of Hayes keyboard dialing commands, therefore, all future references to
AT dialing also mean Hayes keyboard dialing.
Hayes keyboard dialing supports AT-compatible communication software
packages for personal computers. Terminal emulation packages can also be
used with AT dialing.
For originating data calls using an intelligent modem command set (AT)
similar to industry standard Hayes smart commands, refer to Appendix A,
"Hayes standard AT commands".

Extended AT command dialing

This feature provides the user or the user's application software the
capability to originate data calls from a data terminal or workstation to local
and remote hosts and DTE from the MCA. Refer to Appendix A, "Hayes
standard AT commands".

Parameter registers (S registers)

The parameter registers S0 through S12 may be used to program various call
setup parameters. Querying the value of a particular S register may be
accomplished by executing the command, Sr?, where r equals 1 to 12.
Refer to Appendix C, "Basic AT command sets", for information on the
parameter registers compatible for AT dialing.

Learn script file

This feature allows the user to automatically dial the local or remote host
and transmit the login sequence each time this feature is activated.
