# Set the MTU of interface Serial 2/0 to 1,200 bytes.
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial1/0] mtu 1200
physical-mode { async | sync }
Serial interface view
async: Sets the synchronous/asynchronous serial interface to operate in
asynchronous mode.
sync: Sets the synchronous/asynchronous serial interface to operate in
synchronous mode.
Use the
physical-mode
synchronous/asynchronous serial interface.
By default, synchronous/asynchronous serial interfaces are operating in
synchronous mode.
# Set synchronous/asynchronous serial interface 2/0 to operate in asynchronous
mode.
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial1/0] physical-mode async
phy-mru size
undo phy-mru
Asynchronous serial interface view, AUX interface view
size: Maximum receive unit (MRU) to be set, in the range 4 to 1,700 (in bytes).
Use the command to set the MRU for an asynchronous serial interface
phy-mru
operating in flow mode.
Use the
undo phy-mru
By default, the MRU of an asynchronous serial interface is 1,700 bytes.
Note that these two commands only apply to interfaces operating in the
asynchronous flow mode.

command to set the operating mode of the
command to restore the default.
