Using Nokia DKU-5 cable to program picaxe (Working now!)
July 9, 2012
I read this article- http://letsmakerobots.com/node/23728 by Ro-Bot-X and i bought the same nokia cable (CA-42) from a local computer shop. It looked like this from 'outside'.
But wait when i cut opened it it wasn't CA-42!. It was nokia DKU-5 cable based on PL2303,
so i searched the internet for it and found that it was like a predecessor to CA-42 and it does the same thing CA-42 does. So i downloaded the drivers for PL2303 and when connected, my PC shows 'Prolific USB to Serial device' connected. i checked in the device manager and it was there and was assigned COM1. I changed the communications port to COM1 to make my nokia cable a communication port (i have to make COM4 the communication port when i use a serial port) shown here-
Now I cut the cable near the phone connector end and found the TX, RX and the ground wires. So it is now like my half arduino cable (I know two more wires are missing in it but i don't need them). I found this article- http://letsmakerobots.com/node/21245 with which one could program picaxe with arduino cable. So i made that HEX inverter circuit and double checked all the connections, started picaxe program editor and selected COM1 in the ports setting.
So far so good, but when i tried to program a led blink code on it, the error "No hardware found on COM1" came. :(
I tried everything possible at my level- checking all the connections,TX,RX and ground wires of the cable etc but nothing good. I am thinking the problem is with the cable being not supported by picaxe program editor, or maybe i am doing something wrong Please help me getting the cable working!

I finnaly got it working! I think the problem was in drivers as when i downloaded and installed the drivers for the original picaxe USB to serial hub from picaxe website and somehow it started working! here is how it looks like-
