(I am Spanish, excuse my poor English) I have read the entire forum in Spanish, and some of this but I have a problem and can not find the answer: I have a DKU-5 "Made in Thailand" with 5 cables (red, black, white, blue and yellow), I installed the drivers of nokia and appears in fact as COM4 when i connect it. (In the system appears as "Port 1 on Nokia Adapter (COM4)" ) I installed HyperTerminal Private Edition 6.3 and I set it up correctly (.. com4, 38400 8-N-1 N), but when i attempting to connect the cables between them to find Rx and Tx, (and clicking the keyboard) i never see any response in HyperTerminal ... Someone could help me? Thank you very much.
