Asynchronous character-oriented (start-stop) data are transmitted through a synchronous transmission channel at a rate which can exceed the synchronous rate. The excess data rate is accomplished in an input buffer at the transmitter by suppressing occasional stop bits in proportion to the difference between synchronous and asynchronous rates. An output buffer at the receiver detects start bits and thereafter monitors the presence or absence of stop bits. When a stop bit is absent, the output buffer restores it before delivering the character to the data user.
