Usage guidelines
In most cases, a synchronous serial interface uses 0x7E to identify the idle state of the line. You may need
to set the line idle code to 0xFF however to interoperate with devices that use 0xFF (high level of all ones)
as line idle code.
Examples
# Set the line idle code of synchronous serial interface 1/0/0 to 0xFF.
<Sysname> system-view
[Sysname] interface serial 1/0/0
[Sysname-Serial1/0/0] idle-mark
invert receive-clock
Use invert receive-clock to invert the receive-clock signal on the DTE-side synchronous serial interface.
Use undo invert receive-clock to restore the default.
