Hello people, As an assignment for a school-project, i have to make 2 computers communicate with each other over a null modem. A Dutch version of the assignment is online at http://mc303.ulyssis.org/downloads/Opgave2.jpg After some considerations, i guess C is a good language to use for implementation for this project. Next step is figuring out _how_ to do it. I already discovered the Serial-Programming howto, but there is still one important question that i would like to ask: Is it necessary to write a kernel module for this or would this be a major overkill and can everything be done in userspace by just opening and writing to /dev/ttySX ? Any other good pointers aside to the Serial-Programming howto i can look at for this assignment? Thanks for your help, mc303 -- Ing.
