external). An AT modem will not usually

 

establish a session with a remote modem at

 

a speed greater than the speed at which it

 

was set up. The actual speed of the user

 

session is a function of the type of

 

connection that is made between the remote

 

modem and the terminal server modem.

 

Press the space bar until the desired choice

 

is displayed. When the speed you want

 

appears in the field, press Enter key to select

 

that speed and advance to the next

 

parameter.

 

Available baud rates are 300,1200, 2500,

 

4800, 9600, 19200, 38400 and 57600.

User Session

The speed at which the terminal server

 

communicates with its modem.

 

When a connection is made to a remote

 

modem, the modems negotiate the

 

appropriate speed for the link. After the

 

speed has been determined, a message is

 

sent to the terminal server modem such as

 

"CONNECT 2400" or "CONNECT 9600".

 

Normally, the modem switches to the speed

 

in the message. Some modems, however,

 

(and most modems at some connect speeds)

 

do not indicate the speed with a CONNECT

 

message. In these instances, the speed

 

must be derived some other way.

 

Usually an Auto Baud routine is used to

 

sense the speed of the incoming data.

 

Sometimes it is preferable to force the

 

incoming session at a particular speed.

 

CONNECT n sets the speed of the session

 

to the speed in the CONNECT message. If
