There has been an interesting discussion on the Yahoo group LinuxHam,
which is the mailing list for Fldigi, concerning the generation of
Morse on Linux.  Their implementation involves using the sound card
since they can control the timing to a closer degree.  You might check
that group and read the thread archive.

The consensus is that even an RT Linux kernel has limitations due to
timing and that QRQ operation isn't feasable.  How well this is being
accomplished on the Win programs, I don't know.
