Hi!
Trying to get a 8-port serial PCIe card into operation (Exsys EX-44388).
After reboot, dmesg shows:
uart2: <16550 or compatible> port 0x3e8-0x3ef irq 10 on acpi0
and /dev/ has cuau2* devices. It's unclear, which of the 8 ports
is cuau2 (I'll test that later, I promise 8-), but where are the
other ports ?
I've tried to add
hint.uart.3.at="isa"
hint.uart.3.port="0x3e0"
hint.uart.3.irq="10"
hint.uart.4.at="isa"
hint.uart.4.port="0x3d8"
hint.uart.4.irq="10"
to /boot/devices.hint and rebooted, but there are no additional ports found...
I've read
https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/serial.html
and the manpage sio(4). It says to build a kernel with
options COM_MULTIPORT
device sio
which I tried (r343121) and it fails:
/usr/src/sys/dev/sio/sio.c:361:6: error: no member named 't_init_in' in
'struct tty'
tp->t_init_in.c_ispeed = tp->t_init_in.c_ospeed =
~~ ^
So, is sio(4) out of fashion ? What is suggested to get my other 7 serial ports ?
