When all else fails, get out the voltmeter. Do you have power to the antenna? Is it the right voltage? All the way to the antenna?
What volts are on pins 2 or 3 relative to pin 7 in the comm connector? If you see 12 volts, that's RS-422. You may have burned out your computer's serial port. If you see less than 5 volts, that's RS-232 and all should be well, unless you see zero volts. I may have the RS-xxx volts somewhat off because my memory isn't what it used to be. The guy you bought it from should be able to help with comm basics.

I can't seem to establish communications with the Z3805. I tried a null modem as well, in case the cable (supplied) was wired with the wrong connector gender. I see a green blinking light inside, it he left rear corner of the box. Everything is warm, but nothing else. Any ideas?
