It /does/ have hardware flow control. When the space in the input
buffer drops below a certain amount, the MOS asserts the "stop
sending" line. Do you mean /software/ flow control: when the space
in the input buffer drops below a certain value, an XOFF character
is sent?

It's just about as fast as it can possibly be. The core of the
code is a tight machine code loop that does nothing other than
poll the keyboard and the serial input.
 
I'll tidy up the source code a bit and upload it.
