I'm using VB.NET 2003.
Device manager reports that my USB Modem is using COM 6.
For what it is worth the manufacturer has failed over a period of two years
to supply example code or methods.
The example program "VB.NET How-To: Using the Comm Port" does not dectect
COM 6.
The Active X control MSComm32.ocx also fails to detect COM 6 with the
open=true method.
The C++ program from http://www.naughter.com/enumser.html DOES detect the
port using three of six methods tried:
CreateFile method
QueryDosDevice method
GetDefaultCommConfig method
HOWEVER, I am not familiar enough with C++ to translate the methods used to
VB.
Can I get a Visual Basic example using showing similar methods to detect and
open the port the USB modem is using and allow me to send a series of AT
commands to it?
