Hey Guys,

My null modem apparently does not work on the desktop to download bin files with a RS 232 null modem cable. It just keeps on giving me a message saying Downloading and shows 0% forever. I tried the other serial ports and they do not work either.

I have a laptop but no connection for a null modem. Can I connect my null modem to a USB to connect to my lap top to download bin files.

I would appreciate your help.

Trinity seems to say he is attempting to do that from a laptop. Not a PC. Or did I catch his question correctly ?

Othewise he might need a USB to Serial adapter.

OK I goofed. He tried a PC first and wants to use a laptop as alternative if PC does not work.
