Hi Fraser,

There is the source to an older version of the Dev.ser driver that can be obtained here:

http://quics.qnx.com/cgi-bin/search/usr/free/?srch=Dev.ser&submit=submit&select=1

You will be able to use this as a starting point for your virtual serial driver.  Other than that we unfortunately do not have anything else like the QNX6 DDK's.

Best regards,

Erick
