Well from what I know, there have been a lot of Problems with RTS/CTS
flow control with all the Atari range, there are a few Fix programs
for this.
The other problem is runing the serial port faster than 19.2 kbs, this
was to do with the clocking options to the MC68901, if the * 16 clock
option is not on, you don't have the receive data transition resynch
logic enabled, the * 1 clock option is stated just for synch use only.
It could be posible to clock the chip faster, but have not looked at
the Timer 'D' settings.
 
There have been postings from Atari About this, I do have 2 doc files
but don't remember what was in them..
