Hello all, as the title says, this board comes with two internal serial port headers. They show up as COM1 and COM2 in the windows device manager, everything looks ok, but the serial communication fails. Are there any settings I could play with to get this working? At the moment I'm trying to update BIOS, I've tried changing the serial cable connectors on the board, installed windows 7(64bit), tried different serial device .. everything fails.
Normally those serial ports work out of the box with the devices used, never had an issue like this.
Any advice would be greatly appreciate
