Online Command

Mode

This mode is entered from the data mode after the

escape command has been entered. The data com-

munication link remains established but data trans-

mission is suspended. The modem will now accept

commands like it does in the offline command mode.

Data Mode

The modem goes to data mode (online) after it ac-

knowledges the proper signal and successfully con-

nects with a compatible modem. In data mode, the

modem sends and receives data, but will not accept

or execute command instructions.

SENDING

COMMANDS TO

THE MODEM

When the computer, modem, and monitor are on, an

instruction can be sent to the modem telling it what

function or activity to perform. The instruction,

called a command statement, command string, or just

command, is typed using the computer keyboard.

The command statement temporarily resides in a

section of memory called the command buffer.

Each command statement is made up of characters,

numbers, and such keyboard symbols as the & and

% signs. Commands must be written in a specific

form so the modem recognizes and follows the in-

struction.
