WriteFile (hPort, szSend, strlen(szSend), &dwWriten, 0); // send to serial. pay attention into what you want to send.
// if the data has a null in the middle, you cannot use strlen to return the length.

Is that what you need?

No it is not. I am looking for a strict TeraTerm printf module/ command.

I guess what I really need is a serial.c/serial.h that knows how to talk to the 404 and a compiler to compile serial.* into my console programs.

Hello,

You should be able to modify the code that you for the 75401 if by looking in the LH7A404 User Manual and find the UART's data register address.

Thanks,
