2. Model 3830 Modem Installation

Initialization Strings

An initialization string contains several AT commands that are entered at once to program the modem for a specific application.

The following initialization strings identify essential AT commands that directly impact modem operation for a particular application. If you need to modify these strings for your application, make sure additional commands are inserted somewhere in the middle of the initialization string. Whenever an &L command is used, it must appear at the end of an initialization string.

V.25bis Applications

For V.25bis HDLC dial-line operation, create an initialization string with the following commands. Note that the character format can be 8 data bits, no parity, and 1 stop bit; 7 data bits, odd parity, and 1 stop bit; or 7 data bits, even parity, and 1 stop bit:

TYPE: AT&F &D1 &S1 &M234 &W

PRESS: Enter

For V.25bis Bisync operation, create an initialization string with the following commands. Note that the character format must be 7 data bits, odd parity, and 1 stop bit:

TYPE: AT&F &D1 &S1 &M233 &W

PRESS: Enter
