Question 1: I have an internal modem hooked up to the COM2 port of my 6300+. As has been pointed out earlier in this newsgroup, Unix does not come with a device driver for this port. I called the AT&T Hotline and was told that I could find everything I needed to write such a driver in a manual called the "Integrated Software Reference Manual." Has anyone ever seen this manual? Does it really contain everything I need, both to write the driver and to reconfigure the unix boot file? Better yet, has anyone figured out how to access COM2 some other way? I'd like to connect the internal modem to my UUCP utilities. Question 2: I have the standard video board with a monochrome monitor and I'd like to access the screen bitmap from C programs so I can write a graphics package. The Hotline people suggested that I use curses. Somehow, I don't think that will work. Is there some relatively safe way to do this short of opening /dev/mem and twiddling the bits therein. If that is the only way, does anyone know the memory address for the start of the bitmap and the format it is in? Thank you, Michael Braverman braver@ernie.berkeley.edu
