Managing Remote Access Concentrators Using Annex Manager

Chapter 4    Setting Up RACs

4-20

If you select

Autodetect, PPP, ARAP, IPX

, or

SLIP

, Annex Manager does not

allow a RAC to determine modem speed automatically. If you select

Serial,

CLI, Telnet, Dedicated, NDP,

 or

Rlogin

 and the RACs you chose are set to select

modem speed automatically, Annex Manager does not change this
condition.

The

Line Control

 box defines flow control and line speed settings using the

following boxes:

•

Modem Signals

 indicates whether the ports you selected will use

a modem for flow control. When you select this button, the ports
and modem use DCD, DTR, and DSR signals.

•

Flow Control

 specifies the type of signals a RAC uses to control

data transfer. There are four choices:

•

None

 indicates that flow control is disabled.

•

Hardware

 indicates that the modem and/or port use CTS/

RTS signals.

•

Software

 indicates that the modem and/or port use xon/xoff

signals.

•

Other

 displays if the RACs you selected have flow control

set to a value that is not

Hardware, Software

, or

None

. If you

select another setting here, you cannot select

Other

 again.

•

Speed

 defines the baud rate of the asynchronous line between a

device and a RAC. The value you choose must match the
device's baud rate. For a port with a modem, the speed field is
typically set to the maximum speed that the modem supports
(e.g., 115200).

All RACs do not support all port speeds. Refer to your RAC
hardware guide for information
