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. -- Chris
