Hi,

my problem is, that I can download the firmware on the motorola c123, but I can't send a DOWNLOAD ACK. The Firmware is on the Phone, because I see the "HELLO WORLD" example on the phone screen.

I build my own "RS232-to-2.5mm"-Cable and I think it works.... Another thing is, at the end of the download I become permanently the INFO " got 1 bytes ...".

Can anybody help me?

(Sorry my english is very sad :( )

Here is the output:
