I use 2 C routines I found on the net and adapted.
Here is some code I use, quickly ripped out of one of my app, i.e. not re-tested.

(For those who need it, the kext is at sourceforge.net/projects/osx-pl2303.) I am writing a Cocoa app that needs to communicate interactively with a device using an in-house message protocol, as opposed to just sending a file across a link. (If it were the latter case, I would just spawn a process using NSTask and send the file across.)

In this case, I unload the kext using kextunload, and then it works fine. There was a discussion about this at http://communities.vmware.com/message/1073355.
