Not yet, just bought my Lucent card today :)  But that doc section
seemed pretty promising, and even included some sample asm code.  I
couldn't find anything on the codec that is referenced on Lucent's

As an aside, I had considered researching the NT kernel mode driver
API, and seeing how difficult it would be to implement under Linux (as
a userland process, surely...)  It would be great to simply have an
emulator use LTMODEM.SYS and be done with it.  :)
