%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

before the modem disconnects from the telephone line

 

%D0

Disable Delay

 

 

 

 

%Dn
