The UnixWare operating system includes the extended general terminal interface
that supplements the
interface by adding for asynchronous hardware
flow control, isochronous flow control and clock modes, and local implementations
of additional asynchronous features.
termiox(7) is handled by hardware drivers if the board supports it.
Hardware flow control supplements the termio(7) IXON, IXOFF, and IXANY character flow control. The termiox(7) interface allows for both unidirectional and bidirectional hardware flow control. Isochronous communication is a variation of asynchronous communication where two communicating devices provide transmit and/or receive clock to each other. Incoming clock signals can be taken from the baud rate generator on the local isochronous port controller. Outgoing signals are sent on the receive and transmit baud rate generator on the local isochronous port controller.
Terminal parameters are specified in the termiox structure that is defined in the ``<termiox.h>''.
