rpi serial port

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

Is it possible to use the RPI serial port as an ordinary non-console
port? I just tried building a kernel without PLCONSOLE. dmesg shows

plcom0 at obio0 intr 57
plcom0: txfifo disabled
genfb0 at obio0: switching to framebuffer console

so the serial port isn't being used as a console, but which device
corresponds to it? (e.g. ucom0 -> ttyU0) (tried tty00 on the off-chance)

Cheers,

Patrick
