Now I disconnect the adapter with both portmon and the test program
closed.
I run portmon and the COM6/Serial2 is still there, and it is also
under HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM.
Now I reconnect the adapter and now I have two pairs of COM6, one
identified as Serial2 and one Serial4, I am going to monitor the last
added.
This time I will try the test program first.

-------------------------------------------------------
I don't go further since this time the program can't read from the
serial port, please notice the values of baud rate, stop bits and word
length, they are very different from the ones used in the test
program.
Now I try again with Hyperterminal, I select COM6 and everything runs
just fine, I can issue the "+V" command and get the device firmware
version ok.
This is the capture from portmon:
