I'd take a picture of my blackcat i made but I'm to ashamed.
Yours is a Rembrandt mines a load of Jason Pollocks!
I've decided not to give up and have come back with new enthusiasm.
I had so much stuff to read and didnt let it sink in.
The blackcat is a little bit of a con i think.
I've got a tut that tells you how to do it with a max223 and tftpd32.exe
and a terminal emulator.
After doing a few ambits i get the idea and i think i get the idea that tftpd32.exe sends the SB5100_SIGMA-X_1.05.bin and TCNiSO_Bootloader_v2.5.91.bin to the modem.
My only problem at the moment it understanding where to put what wires to the modem.
It makes it a little bit more confusing that I've got a max233 and the tuts are about the max223.
I'm not that bothered if i break it.
I got ?? 3 others to keep me going until the blackcat gets here.
