Configuring a link device
A link device is a physical device
such as a modem, a synchronous or an asynchronous
ISDN channel, or a directly-connected serial line.
The link devices that are defined for a bundle control which devices it can
use to establish an outgoing or incoming PPP link.
You must have already configured the communications devices
that you want to use as link devices with PPP.
Suitable devices are modems,
ISDN terminal adapters,
and dedicated serial lines.
``Adding and configuring modems'',
``Adding ISDN devices'',
``The Serial Manager''
for more information on how to configure your system for such devices.
To modify the settings for a link device:
In the PPP Manager,
View Link devices
to view the currently defined link devices.
To change an existing link device definition, select
the link device from those listed, and then select
You can change the following information about the link device:
Whether the device can be used by bundles. Set to No to
prevent PPP using the device.
The type of flow control that will be used with a link device:
Do not use flow control.
Use RTS and CTS handshake lines to perform flow control.
Use XON and XOFF characters to perform flow control.
Flow control settings are not shown for synchronous ISDN channels
as they have no meaning for such devices.
