Interrupt sharing on ISA requires special magic.

I think if you configure no irq at all, it will automatically
go to polled mode.
Not sure if uart(4) can actually do that, sio(4) could.

Hello, Freebsd-current.
I've built new router based on Intel D2500CC motherboard. It contains
four (!) UARTs. Two of them are D-SUB9 on back panel, two others are
only headers.
This motherboard contains PS/2 keyboard and VGA too.
I'm trying to get com console on one of D-SUBs.
All UART
37 matches
