You can only normally have 2 serial/com ports com1 and com2 if you
have more then they double up so com1 and com3 are the same com2 and
com4 are the same. So if anything is using the IRQ for com two you
cant have com4 working.

Try disabling all the ports in the bios if you are not using them and
check for anything on com 2 like a modem bluetooth etc
