Hi

I'm trying to use the RS485/COM2 port on an embedded Axiom SBC84500 card
running kernel 2.4.26. I have configured the JP9,JP10,JP10 according to the
documentation but there is no output signal when writing to /dev/ttyS1.

I read somewhere that I should use ioctls to write to the port instead of
the standard write function.

Anybody can help ?
