This series of WIP is also good for testing. But for next version of WIP I need to know something from Jean about his i2c-parport. For all other drivers using the parallel port, they are choosing which port to use. But i2c-parport is not specifying that. So as a result, in my test system which has multiple parallel ports, when I load the module, i2c-parport is claiming all the ports with exclusive access. So if i want to use i2c-parport on one parallel port and any other device on another port then that is not possible. If that is the intended behaviour then I need to change some parts in the way I was making the parallel port device-model. Anyways, I have mailed Jean yesterday, and waiting for his comments now. Adding cc to Jean also to this mail. >I just picked up a backpack CD-ROM drive on ebay > for 99p as well 8) wow, share me the link please. I will also get one. I am able to manage only one parallel printer and staging/panel for testing. I am looking for a parallel port zip drive or cdrom or scanner to manage and test the code better. but :( regards sudip > > Alan
