support for Oxford Semiconductor OXPCIe952 / 16950-compatible UARTs
I recently upgraded my main FreeBSD machine, and bought a cheap Rosewill
PCI-e dual UART card to replace the old PCI card. I'm having problems
getting anything to work, though, as programs like tip hang when doing a
TIOCSETAW to set parameters; ^T says "ttyout" as the wchan. I have a
modem attached to one port, an antique serial device on the other; they
act the same. Has anyone seen this, or figured out how to get past it?
Some Googling hasn't yielded any recent results.
The details:
dmesg:

Thanks in advance,
