Serial I/O Logic Unit. This logic unit provides the user with two separate serial I/O chan-
nels that are completely compatible with the Z84C4x SIO (see Figure 5). Their basic func-
tions as serial-to-parallel and parallel-to-serial converters can be programmed by a CPU
for a broad range of serial communications applications. Each channel, designated Chan-
nel A and Channel B, is capable of supporting all common asynchronous and synchronous
protocols (Monosync, Bisync and SDLC/HDLC), byte- or bit-oriented.
