Your dmesg shows the serial port is detected as:

> pccom1 at isa0 port 0x2f8/8 irq 3: ns16550a, 16 byte fifo

So you should be using tty01.

Maybe nc(1) and tip(1) would do:

tip -4800 tty01 | nc -lk 12345

Then a TCP connection to port 12345 gives:

$ telnet tosh 12345 
Trying 127.0.0.1...
Connected to 127.0.0.1.
