>Is it possible to do synchronous communication with the Serial Driver?

Theoretically yes.  However, in reality, there are so many things that
turn off interrupts (e.g. the Sony floppy driver, AppleTalk drivers, etc.)
which make life a living ...  well you get the message.

You need to directly bang on the SCC to do synchronous communications through
the serial ports.  This is also a nono since the SCC may not always be
accessible.  

Sorry for the bad news.
