Thank you Mike for your tips but NanoBSD in my situation is a read only system because its stored on a flash card and copied in to RAM during the boot sequence.
I don't see any UART in the boot messages. This the result of the # dmesg | grep -E "^sio[0-9]" command. sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0 sio0: type 16550A, console sio0: [FILTER] sio1 at port 0x2f8-0x2ff irq 3 on isa0 sio1: type 16550A sio1: [FILTER] These are the only on board available serial communication channels. Does have anyone else a useful tip? Thanks.
