The I/O address and interrupt are assigned to the card by the "Plug and play"
system of the PC. These values CANNOT be changed with the current version
of the driver.
The Force Configuration radio button enables you to force the I/O address and
interrupt and is usually used only for legacy devices which require specific
settings. This is an advanced feature which should only be tackled by experieced
users.
In this window, the COM port assignment may be changed, simply by selecting
a new COM port value from the pull down menu relevant to the port. However,
COM port usage other than those for the PCI 1 Port RS232 card itself are not
checked, so it is advisable to first check which COM ports are in use - port
availability can be checked by viewing the
Device Manager window:
All COM ports present will be listed under the entry "
Ports (COM & LPT)

The above screenshots indicates that COM2 - 4 and COM6 and above are not
installed, and therefore may be used.
