I am working on a project for my Advanced Operating Systems class which requires adding the Microcom MNP 2 and MNP 4 protocols into the Asynch Comm Driver in Mach OS. The purpose being to support in software the error correction protocols which are found in newer modems but are non existent on older modems which are otherwise just as good as the new ones. While I have been able to get hold of the Microcom Specs I have been unable to figure out where in Mach the Asynchronous Driver is located, and whether or not I have the source for that part of the OS. I believe it will be an easy job to rewrite the driver if I am able to find the sources. I am using Mach release 2.0 on a Sun 3/50 setup as a stand alone system. In Mach OS, are device drivers in the Kernel or are there ways of providing loadable modules for hardware device drivers? Thanks in advance for any assistance you are able to provide.
