I got one piece of modem card,what should I connect to the modem port to test?
does passmark sell it?
if i got 2 units,could i use a telephone line/cable to link them then run passmark modem test software?
I couldn't find any user manual of this software.

There is a comprehensive help file that comes with the software. (click on the help button).

You can do an internal loop back test (no external connection required) or you can test with two modems.
