serial mouse or external modem to parrarel port??

[booger]

is it possible to use a serial mouse on a parrarel port because i have bought the adapter but neither the modem nor the mouse work in the parrarel port,anyway how do i make it work,i need to have either the modem or mouse on the parrarel port cause my old laptop computer only has one com port(external) and the trackball mice is not working(it broke)
