the communication technique) and outputs a composite serial
stream of data on the TxD output pin.
Modem Control
The modern control section provides interfacing for three input
signals and three output signals used for “handshaking” and status
indication between the CPU and a modem.
SYN/DLE Control
This section contains control circuitry and three 8-bit registers
storing the SYN1, SYN2, and DLE characters provided by the CPU.
These registers are used in the synchronous mode of operation to
provide the characters required for synchronization, idle fill and data
transparency.
