CD did not come in box

I purchased a PortServer TS M MEI Modem and the installation CD was not in the box. I contacted support and was told I had to pay extra for them to tell me how to get the CD. I have searched this site and cannot find what I am looking for. Can someone tell me where I can get this? Thanks.

You’ll want to start with the Device Discovery for finding/configuring the unit:

If the RealPort driver is going to be used, it can be downloaded here (select your OS version from the drop down):
