3Com Router Command Reference Guide — V1.00control on this interface. The outbound direction refers to the direction in which thedata flow out from the router. It means that this interface implements flow control onthe attached device. Hardware and software flow controls cannot be simultaneouslyused in the same direction. If configuring the software flow control in a directionalready configured with the hardware flow control, the hardware control will beremoved, and vice versa.For related commands, see async mode.Example# Set software flow control on the interface Async 0.[3Com-Async0]flow-control software3.1.10 idle-markSyntaxidle-markundo idle-markViewSynchronous interface viewParameterNoneDescriptionUsing the idle-mark command, you can configure the idle coding of synchronousinterface to "7E". Using the undo idle-mark command, you can restore the idlecoding of synchronous interface to "FF".By default, the idle coding of synchronous interface is "7E".In general, the synchronous serial interface uses the code "7E" to represent the idlestatus of the line, while some devices use the code "FF" to represent the idle statusof the lines. To improve the compatibility with the equipment, you need to change theidle coding of synchronous serial interface.Example# Set the idle coding of interface Serial0 to "FF".[3Com-Serial0]idle-mark26
