Has anyone managed to use KSDK CDC Example with Windows WriteFile?

Hi,

 

I have tried to use WriteFile to send a short string of eight characters from a Delphi program and c#.  Both of them lockup and writefile never returns .  However, using a terminal program (realterm), it works perfectly!

 

A breakpoint on the CDC callback is never hit when writefile is called.  However, it is hit many times when the port is opened!

 

Has anyone managed to use the KSDK CDC with a windows program that uses WriteFile?  Specifically I am using the Composite CDC and MSC example on K24.  

 

HEEELLLLPPPP!!!!!!!!!

 

Ashley
