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 ? -- pi@opsec.eu +49 171 3101372 One year to go !
