if you want to use more than two modems i think that you must buy an
i know that you can't use com1 and com3 and com2 and com4 together so even
with 4 com ports you can use only two ports at same time. this because
com1/3 shares the same irq4 and com2/4 shares the same irq3.
there is an hardware that conncet 8/16 modem's com ports to one pc's com
You can use different modems with usb!
