COURIER HIGH SPEED MODEMS

Register

Default

Function

 

 

 

Setting S28 to zero eliminates the extra

 

 

tones, resulting in a faster connect time if,

 

 

for example, the modem is set to use V.21

 

 

modulation (300 bps) or V.23 modulation

 

 

(1200 bps).

 

S29

20

Sets the duration, in tenths of a second, of

 

 

the answer tones sent during V.21 hand-

 

 

shaking. Default = 20 (2 seconds). This

 

 

gives V.21 modems additional time to

 

 

connect in V.21 mode before timing out.
