I currently have a serial device attached to the bottom connector on my
Viewsonic V37 pda. I am trying to read the strings sent by the device and so
need to attach to the correct com port.

How can I determine which com port is assigned to which device

regards, Mike
 
Use CE Remote Registry Editor to explore HKLM\Drivers\Active\ registry
key. Here you could find list of available COM ports for your device e.g.:

....Active\07\:- Name = COM1:, Key = SER2410
....Active\08\:- Name = COM2:, Key = IRDA2410

Hi,

The built-in comport on the V37 is Com1. What sort of problem are you
having?

You may not realize that the serial cable that is furnished by Viewsonic is
designed to connect to a PC (for use as an ActiveSync connection). Thus, if
you want to connect your V37 to some other device, such as a modem or
instrument, you must add a null-modem adapter in series with the cable.
Such an adapter costs about $10.
