A non-zero value will set the data rate to a given value
in asynchronous mode,
and will set the date rate and internal clock source of synchronization

A zero value is equivalent to specifying the
.Cm extclock
option.
The transmitted data (TxD) are synchronized using the internal on-board timing
generator, the internally generated timing signal is driven on the TXCOUT pin,
and the signal on the TXCIN pin is ignored.
This mode is used for direct
terminal-to-terminal communication, e.g., for connecting two computers together
in a synchronous mode via relatively short cable.

On new
models (Tau32-PCI, Tau-PCI/2E1 and Tau-PCI/4E1) this configuration means single source
of synchronization and passing all unused (in both channels) timeslots from
one channel to other.
