having got the hardware module for the RS-232 today, pin were scratched
from
the direct contact with the cable, me idiot! but I think it works right now:

pcistat -t:
ttyu0 23040    0    0 2304 23064   39 2307     7  1933  1933 ICOil

dmidecode -t connector:
Handle 0x0021, DMI type 8, 9 bytes
Port Connector Information
        Internal Reference Designator: COM1
        Internal Connector Type: DB-9 male
        External Reference Designator: Not Specified
        External Connector Type: None
        Port Type: Serial Port 16550A Compatible

recoginzed but not configured?


sudo sysctl -a | grep 'uart.0'

dev.uart.0.wake: 0
dev.uart.0.rx_overruns: 0
dev.uart.0.pps_mode: 2
dev.uart.0.%parent: acpi0
dev.uart.0.%pnpinfo: _HID=PNP0501 _UID=1 _CID=none
dev.uart.0.%location: handle=\_SB_.PCI0.LPCB.UAR1
dev.uart.0.%driver: uart
dev.uart.0.%desc: 16550 or compatible

tomorrow I'm moving house but Thursday is quite a good time to try it out!
thx
