COURIER HIGH SPEED MODEMS

 

&S2

This option is for specialized equipment such as

 

 

automatic callback units. On loss of carrier, the modem

 

 

sends a pulsed DSR signal with Clear to Send (CTS)

 

 

following Carrier Detect (CD).

 

&S3

This is the same as &S2, but without the CTS following

 

 

CD.

 

&S4

The modem sends the computer a DSR signal at the same

 

 

time as it sends the Carrier Detect (CD).

&Tn

Modem testing

 

&T0

End test

 

&T1

Initiate Analog Loopback (AL) testing

 

&T2

Reserved

 

&T3

Initiate Local Digital Loopback (LDL) testing

 

&T4

Grant Remote Digital Loopback (RDL)

 

&T5

Deny RDL

 

&T6

Initiate RDL testing

 

&T7

Initiate RDL with self test and error detection

 

&T8

Initiate AL with self test and error detection

&W

Write the desired template to NVRAM, using the &W

 

command.

 

&W0

Write to NVRAM template 0

 

&W1

Write to NVRAM template 1

&Xn

Synchronous transmit clock timing signals setting. Determines

 

whether the modem or DTE will generate the timing signals.

 

&X0

The Courier is the source of the Transmit clock timing

 

 

signals and sends them to your DTE over the RS-232

 

 

interface. The DTE rate will follow the connection rates.

 

 

Default.
