flexfax: sun se0: Buffer overrun problem; serial port hardware recommendations

[gary@sabot.com (Gary Sabot)]

I've encounted a sun solaris 2.6/ultra60 bug, bug id 4148839:
   "WARNING: se0: Buffer overrun"

It causes hylafax to receive faxes that result in lots of fax2ps
errors followed by scrambled/shredded output, as if horizontal hold on
a TV was misadjusted.  Everything else works fine.

I believe I have hardware flow control set up correctly, especially
since Sun's method of replicating this bug does not involve hylafax
(and I get it from uucp too, but uucp error correction handles it OK).
Since the bug seems to just happen with new hardware and software and
first appeared on sunsolve a few days ago, it may be a while till
there is a fix.


Can anyone recommend a way to easily add one or two serial ports?  Any
good or bad experiences with particular brands of SCSI, ethernet, or
PCI add-ons?  They all seem to cost a few hundred dollars, but
ethernet seems like it might be the easiest to configure.
