[Dx4win] How to identify serial ports on new computer?

[Larry Alkoff]

My trusty old Windows 98SE computer was destroyed by lightning.

I have pressed into service a reliable Windows XP Pro computer.
Since it only has 1 serial port, I installed a CyberPro PCI 4S which 
contains 4 serial ports, 2 on a PCI board and 2 more on a bracket that 
plugs into the PCI card.

The additional ports are labled serial 8 through 11.

How can I identify the extra serial ports so I can assign them in DX4Win
to rig control, Rigblaster and MMTTY?

I really don't want to plug serial ports in willy-nilly because I fear 
breaking something.

I have a break-out box and may try jumpering serial pins 2 and 3 to see 
if any lights blink but I'm hoping for another method.

Please help, _ really need Glorioso!
