To fully test the installation of your Fastcom: 232/8-PCI, you will need to build a "loop back plug".  Materials 
needed are a DB25 female receptacle, solder cup style, and a few short pieces of 20 or 24 AWG stranded wire.  
This loop back plug can be used to test any RS-232 port.  Jumper the pins together on the DB25 as illustrated 
below:

4 RTS 
5 CTS 
6 DSR 
8 DCD 
20 DTR 

 
 
 
 
 
 
 
 

TESTING YOUR FASTCOM ASYNC PCI PORT IN WINDOWS

 

 
These instructions assume that you have already installed the card and have followed the installation instructions.  
The SERIALGT.EXE program (98, NT) or the Device Manager (2K, XP) should show the boards/ports that are 
installed, and the COM numbers assigned to those ports. 
 
1.  Attach the “octopus” cable supplied to the DB37 connector.  Install the loopback plug on the port to test.
