&C0

 

Force DCD active

 

 

 

&C1

*

Allow DCD to follow carrier state

 

 

 

&D0

0

In asynchronous mode (&Q0), the modem ignores DTR.

 

 

 

1

The modem switches from data mode to command mode when an on-to-off transition of DTR occurs.

 

2*

An on-to-off transition of DTR causes the modem to go on-hook (hang-up) and disable auto-answer mode. Auto-answer mode (S0 is not equal to zero)

 

 

is enabled when DTR is turned on. *

 

 

 

 

3

An on-to-off transition of DTR re-initializes the modem. The re-initialize procedure performs a power-up reset, except that the UART registers are not re-

 

 

configured. DTR option

 

 

 

&F

none

Load factory defaults

 

 

 

&G

0*

Guard tone disabled

 

 

 

 

1

550-Hz guard tone enabled.

 

 

 

 

2

1800-Hz guard tone enabled.

 

 

 

&J

0

Auxiliary relay is never operate

 

 

 

 

1

A lead is connected to the A1 lead the modem is off-hook

Make = 39%; Break = 61% for use in the United States. *

 

 

 

1

Make = 33%; Break = 67% for use in the United Kingdom and Hong Kong.

&Sn

0*

Force DSR alway active

 

 

 

 

1

DSR circuit is on during handshaking, off in test or idle modes. DSR is on when carrier is lost.

 

&Tn

0*

Terminates test in progress

 

1
