Help with serial ports.

Hi,
This is my first post here.
I would like to ask: how to connect the barcode scanner to the serial port?
What are the names in the system (in / dev) and serialport1 serialport0?
Please help with this.
Regards.

We know nothing about your OS, architecture and model...

Yes, you're right.
Too little information I have given.
I have HP-UX version 10.20 on a HP B180 controler.
Already solved my problem by drawing on this document:
pbraun.nethence.com/doc/sysutils_hpux/hpux_serial.html
Is very helpfull.
I now have some new problems ...
Regards.
