Hi all, I may have just gotten some insite to the serial problems with 1.1 on the
mac.  I was talking with a co-worker and he mentioned that the Sun serial driver
handled handshaking badly.  Actually it handled
transmit handshaking fine, but payed no attention
to receive handshaking.  Specifically, it never dropped RS causing lots
of fifo overflows, just like we've been seeing on NetBSD.  I dont know
exaclty how much the current serial driver is based on the Sun3 SunOS3.5 driver,
but the error messages zs0a seem to say it is, at least in some part.

One way to see is for ppl to payattention
and see if fifo errors occur
during large file "puts"
