Serial, Aux, And Am Interface Configuration Commands; Async Mode - HP MSR series Command Reference Manual

Examples
# Shut down serial interface Serial 2/0.
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial2/0] shutdown
Serial, AUX, and AM interface configuration
commands

async mode

Use async mode to set the operating mode of the current interface.
Use undo async mode to restore the default.
Syntax
async mode { flow | protocol }
undo async mode
Default
An asynchronous serial interface operates in protocol mode and an AUX interface operates in flow
mode.
Views
Asynchronous serial interface view, AUX interface view, AM interface view
Default command level
2: System level
Parameters
flow: Configures the interface to operate in flow mode, or named interactive mode. In this mode, the two
ends interact attempting to set up a link after the physical link is set up. During this process, the calling
party sends configuration commands to the called party (this is equal to the operation of manually
inputting configuration commands at the remote end), sets the link layer protocol operating parameters
of the called party, and then sets up the link. This approach applies to man-machine interactions such as
dial-in access.
protocol: Configures the interface to operate in protocol mode. In protocol mode, the interface uses
configured link layer protocol parameters to set up a link with the remote end after its physical link is
established.
Usage guidelines
You can configure PPP when the asynchronous serial interface is operating in flow mode, but the
configuration does not take effect. The PPP configuration takes effect only after you change the operating
mode of the interface to protocol.
Examples
# Configure asynchronous serial interface 1/0 to operate in flow mode.
<Sysname> system-view
[Sysname] interface async 1/0
