Hi Rafael, you probably only have to configure the third serial port COM3 in 'DOS language' or '/dev/ttyS2' for Linux.
To do this make sure the 'setserial'-package is installed. Then open the file '/etc/rc.boot/0setserial' with your favourite editor. Goto the line that says: #${SETSERIAL} -b /dev/ttyS2 ${AUTO_IRQ} skip_test autoconfig ${STD_FLAGS} and remove the comment sign '#'. You might also want to set a higher interface speed. Consult the setserial manpage with 'man setserial' Execute the script - reboot or just type '/etc/rc.boot/0setserial<enter>'. (Is there a reason why the latter shouldn't work?) That's it! The only thing you need is a decent terminal program like 'minicom' or 'seyon'. Just a remark: In case you want to use the serial driver in the kernel as a module it is important to use the standard values for io and irq. And I'm not sure if this will work for COM3 and COM4 at all when using a module. (Probably it does - anybody has more knowledge on this?)
