Hello,

The problem with onboard serial ports on macppc were purely
interrupt-related as far as I can tell, when we overhauled the interrupt
handling code about a year ago the serial ports suddenly became usable.
I couldn't test more than 38400 bps but sending a couple megs back and
forth at that speed didn't generate a single zmodem retransmit. The old
code would simply lose LOTS of interrupts, it was sort of stable up to a
few hundred interrupts per second but apparently the way the current
driver handles the ports will generate a few thousand interrupts per
second when transferring data at higher speeds ( no idea if it uses DMA
- probably not ). The new code is definitely in 3.0 and I /think/ it's
been pulled into 2.1 as well.

have fun
Michael
