ot memory allocation question

[Don Raikes]

Hi Chris and all those who were of such great help last week.

Just wanted to let you all know that with your help and support, plus a link from a fellow classmate I was able to get the assignment finished and turned in 3 hours early.

Of course after spending over 60 hours on this assignment, my prof sent out a note this morning saying that he wasn't expecting for the students to spend more than 10 hours on an assignment :-)

No.  We discussed this several years ago, and we concluded that it won't work.  It's pretty much infeasible to use the tty devices (/dev/ttyS*) from kernel space.  That discussion might be available in the list archives.  I've been told that the solution to our serial problems in Speakup is to write a tty line discipline.  I don't really understand how to do it.
