did anybody in the freescale forum already testet the above example "How to Run the Point-to-Point (PPP) Example Application" with the following parameters:



- TWRK60N512 with TWR-SER1 using ittyd and the PE micro console as my stdio (TTYF).

- IAR Workbench

- rtcs_shell_twrk60n512 example


- Laptop with Windows XP


I rebuild all mqx files. ITTYD is set to 1


On the shell I'm using the command: "PPP client ittyd", like it is described.


My PE micro console is giving me:

"Please wait initiate PPP connection. Waiting...."


And after a while:


"Error: The connection attemp failed because the modem (or other connecting device) on the remote computer is out of order"


I'm getting no reaction on the PC's side.


I'm testing (also with an oscilloscope) with HyperTerminal on the Laptop, if any ascii codes are send by the serial port of the TWR-SER1- board. No data at all.


Shouldn't there at least some ascii characters coming out of the serial port!?


Does anyone have an idea, why the client is not sending any data to establish the ppp connection as a client?

Does anyone know where to look in the port driver, what it is doing?

Does anyone have other ideas, how to test and what to test or visualize?


Thanks for any hint or help


all the best
