USB to Serial Converter on Serial Modem


How do I set the USB to Serial Converter to recognize a serial modem? I know that the converter is recognized because when I try to open USB View it is displayed correctly as "prolific usb to serial controller".I even tried to transfer the connection between the 3 usb ports I have and it also is recognized on all 3.
when I connect a serial modem the modem does not work.I do not know how to configure it to be "seen" as connected to the converter.

PLease help me!

Maybe the kenel module isn't loaded. In the lsmod output you should see a module named pl2303. If it's not there try this command as root:

Code:
modprobe pl2303

Yes I did that.and in addition "modprobe usbserial".no effect at all.It is even listed when I do lsmod. But when I try to use kppp the modem is not responding.It says modem ready but there are no lights indicating activity.
Then I removed the modem from the usb to serial converter.It still says "modem ready" so it is not detecting the modem itself but instead it is detecting the converter circuit as a modem.
I confirmed this when I disconnected the usb to serial conv.The "modem ready" signal disappeared.I get a "unable to query modem".
the usb to serial converter works perfectly on xp BTW.
