&Sn

Data Set Ready (DSR) Option

This command selects DSR action.

&S0:

DSR always ON  (default).

&S1:

DSR comes on when establishing a connection and goes off when the connection ends.

Result Codes:

OK

n = 0, 1

ERROR

Otherwise

&Tn

Self-Test Commands

This command allows the user to perform diagnostic tests on the modem.  These tests can help to isolate
problems when experiencing periodic data loss or random errors.

&T0

Abort. Stops any test in progress.

&T1

Local analog loop.  This test verifies modem operation, as well as the connection

between the modem and computer.  Any data entered at the local DTE is modulated, then
demodulated, and returned to the local DTE.  To work properly, the modem must be off-line.

&T3

Local digital loopback test.

&T6

Remote digital loopback test. This test can verify the integrity of the local modem, the communications
link, and the remote modem. Any data entered at the local DTE is sent to, and returned from, the
remote modem. To work properly, the modems must be on-line with error control disabled.

Result Codes:

OK

n = 0

CONNECT

n = 1, 3, 6

ERROR

Otherwise
