Re: COM3 on X86 Platfom

Well, make absolutely sure the IRQ and port are set correctly in the
registry and match the BIOS. Are you using a serial port for debug? In
that case what's in the BIOS doesn't match CE (name wise):

BIOS COM1: --> CE Serial Debug
BIOS COM2: --> CE COM1:
BIOS COM3: --> CE COM2:

Just keep that in mind as well. Apart from that, debugging is really the
fastest way to discover what's wrong!


Good luck,

Hi Mike

Sorry, let me explain better: COM3 is accessible but I can't receive/transmit
anything. No loopback from COM3.

BSP_SERIAL3 is set and my settings are there. I checked them with a registry
editor directly on the
platform. Any other suggestion before debugging?

You can't see COM3, meaning the driver for COM3 is either not loaded or
fails during initialization.

1) Check if BSP_SERIAL3 is set
2) Check if all settings are as you expect in reginit.ini and ce.bib in
your FLATRELEASEDIR
3) Build a debug image and set a breakpoint in the Init function of the
serial driver and wait for index 3 and see what's breaking.

Good luck,
