%C

 

Data Compression (DC) Mode

 

 

Determines whether the modem implements methods of

 

 

increasing the effective data rate by reducing the number

 

 

of bits used to represent data

 

%C0

Disable Compression

 

 

 

 

%C1

Enable Compression

 

 

 

%D

 

Disconnect Buffer Delay

 

 

Controls the delay after detection of a disconnect request

 

 

before the modem disconnects from the telephone line

 

%D0

Disable Delay

 

 

 

 

%Dn

Delay for n Seconds (n = 1 to 255)

 

 

 

%L

 

Minimum Modulation Rate

 

 

Sets the minimum rate that the modem uses when con-

 

 

necting in a data modulation mode.

 

%L0

Minimum modem rate that the modem supports(300 bps)

 

 

 

 

%L1

300 bps

 

 

 

 

%L2

1.2 Kbps
