Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Install busdog on Windows 32bit
2. Install a printer on LPT1
3. Run busdog, select parallel port, start capture
4. Send a job to printer

What is the expected output? What do you see instead?
Expect to capture data sent to printer, no activity is captured on busdog

What version of the product are you using? On what operating system?
0.2.1-32bit. Tested on Windows XP and Windows 7, same behaviour on both.

Please provide any additional information below.
Have tried serial ports, they work fine, just parallel port doesn't work.

busdog does not trace any parallel port specific ioctls (probably just 
read/write calls), unfortunately at the moment I dont have any parallel port 
devices to test with.

Have you tried portmon 
(http://technet.microsoft.com/en-us/sysinternals/bb896644.aspx)?

I'm not interest in ioctls just read/write calls. I'm writing a diferent GUI 
based on busdog and portmon isn't an option :(.

Probably you can use VMWare Player to test it, you can add a virtual parallel 
port on guest OS that maps to a file on host OS.

I'm not a WDD developer, but I'll be happy to help if you want.

I have now got VMWare player and have mapped the parallel port to a file on the 
host... however I am having trouble finding a parallel port program that will 
cause data to be written to the mapped file.

You can copy a text file to LPT1: port on guest OS using command prompt. 
Something like:

COPY <some text file> LPT1: /b

You will see your text file on host OS grow up.

Yes that works. I am not sure why busdog does not pick up the write irps, I 
will have to investigate
