Modem

Commands

Description

&Ln Telephone line type

0 Switched dial-up telephone line (default)

1 Leased line

&Pn Pulse make/break ratio

0 39/61 ratio at 10 pulses per second (default)

1 33/67 ratio at 10 pulses per second

2 39/61 ratio at 20 pulses per second

3 33/67 ratio at 20 pulses per second

&Rn Clear to send signal status

Controls the Clear To Send (CTS) signal during synchronous

operation. During asynchronous command and Data Modes, CTS is

always ON.

0 CTS signal tracks the Request To Send (RTS) signal (default)

1 Modem ignores RTS and keeps CTS active continuously,

regardless of RTS status.

&Sn Data Set Ready signal status

0 DSR signal always ON (default)

1 DSR signal is ON during handshaking and OFF in test or idle

mode. DSR is OFF when the remote carrier signal is lost

&V View any stored configuration profiles

&Wn Write S register values to one of two profiles

The following commands and registers can be stored in nonvolatile

memory :

Commands : Bn, Cn, En, Ln, Mn, Qn, Vn, Yn, Xn, &Cn, &Dn, &Gn,

&Ln, &Pn........

0 Write S register values to profile 0

1 Write S register values to profile 1

&Xn Synchronous clock source

This command is ignored during asynchronous operation.

0 Modem supplies its internal clocking signal on EIA pin 15 of its

RS-232-C connector

1 Modem accepts an externally provided clocking signal from your

DTE on EIA pin 24 of its RS-232-C interface

2 Modem drives its transmit clock from the receive carrier signal

and applies it to EIA pin 15 of its RS-232-C interface

&Yn Select stored profile on power-up reset

This command tells the modem which profile to use the next time the

modem is turned on or reset.
