Date: 30 Mar 1994 04:24:45 GMT Organization: North Carolina State University Lines: 17 Message-ID: <2nauud$g2i@taco.cc.ncsu.edu> NNTP-Posting-Host: c00313-11pa.eos.ncsu.edu Cc: I have recently aquired enough diskspace that I can contemplate poking around inside the kernel of a free Unix flavor or two. As I have a few RT PC 8 port serial cards with okay hardware documentation I am contemplating seeing if I can write an appropriate driver so that it can be supported (Probably with a bit of surgery on the card). Where can I find some good tips on going through the specifications of registers on the card to working on a driver? For that matter where can I get some tips on writing a device driver for FreeBSD? (Outside of 68000 assembler this is my first attempt at writing a device driver). Thanks. -- "Very Pete Townshendish." "Who?" "Exactly." cddukes@eos.ncsu.edu cdukes@nyx.cs.du.edu pakrat@vnet.ibm.com
