The conf utility connects to the board fine and displays all settings and realtime data. This GUI fails to connect.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Fire up he program and try to connect.
2.
3.

What is the expected output? What do you see instead?
I expect to connect but instead it asks whether I have input the port 
correctly. What might not be common is that my board is on COM19. This appears 
correctly in the dropdown to select a port.

What version of the product are you using? On what operating system?
2.2 on WindowsXP Pro, but 2.3 fails in the same way.

Please provide any additional information below.
I think it might be that the comport is too high. This same setup works fine on 
my Dell Inspiron DUO on port COM3

Just to clarify: I do ensure that the port is not in use by another program.

Definitely a serial driver issue... however:
Please try on Win7 or Win8... XP is End Of Life opsys, so winGUI will not 
support it in the future.

If it was a serial driver issue then the Conf utility would also fail. As it is 
only this program fails. I suspect that the highest port supported will be 
com15 (4 bit storage).

MultiWiiConf uses Java with the provided Java serial library.
WinGUI uses direct .NET serial library which connects directly to FTDI drivers
Com port number passed as a string so it is not a port number issue (my test 
enviroment uses com49.....

I do not have the source to look at, but I would be really surprised if Java 
did not use the installed device drivers, especially as it is portable between 
many platforms. As far as this problem is concerned, both Conf and the Arduino 
IDE work fine and all the other bits of software I have that use serial/USB 
communication, so I would be amazed if it is a driver problem. This GUI program 
is the first software that does not work, so I strongly suspect a problem in 
the software.

Note that I realise you do this for free and I am not ungrateful, just trying 
to sort out the problem. I would be happy to provide debug information if there 
is anything I can do to document the problem better. Unfortunately I am a Linux 
user and have only got a Windows partition for programs that don't run under 
Linux or in Wine under Linux.
