Hi Netters, I am having a problem writing a device driver for a at&t 3b2, running Unix 2.0. This is my first attempt to do write a driver. I get a "PANIC trap occurs" message every time I try to read a text file after opening in the READ entry point in the device driver. The error message points to a prblem in MMU (ie memory management unit ) You might think this setup is unusual because this is not a service provided by the kernel to the driver, but I need to do it. So my question is why this occurs and what is the way around it? i.e. how else can I read a file in my device driver. Thanx -mani mani@csun1.cs.uga.edu or mani%csun1.cs.uga.edu@gatech.edu
