Y Asynchronous/Synchronous Mode Selection
Y0
Asynchronous mode. No speed buffering, no protocol.
Y1
Synchronous mode. No speed buffering, no protocol.
Y4
Quasi-Synchronous mode. Allows the transmission and reception of
synchronous data through an asynchronous DTE by stripping off start and stop
bits on transmission and adding them on reception (See V42 operation).

Y6
Asynchronous with speed buffering. Allows fixed DTE-DCE speed so
applications do not need to change the communications rate based on
connection results.
