You have to set the interface up, for the serial connection you require.
That is what getty does. There is more than the baud rate.
setserial can do some things, otherwise you need to program it.
There are countless example programs and FAQs out there that show how to
program the Linux serial interface, it is the same as on any other linux
system - google is your friend. It is also a FAQ here so searching the
group for stuff on serial use should help too. In fact, in the gzipped tar
file I sent you re. an adc program, there is example rs232 source code!
