My point is that, if the person is trying to program an HT1000 under Windows, solving his serial adapter issue doesn't solve the problem. HT1000 RSS (like most of the older RSS) will appear to run under a Windows "DOS Window", and you can open and edit a codeplug, but when you try to write to the radio you risk corrupting it. This happens because Windows will intercept the RSS's direct UART controls, causing bad bits to go to the radio. Since the RSS and HT aren't using RS232 protocols, you won't be able to correct the corruption by trying another overwrite. Usually the radio has to go back to Depot for a new MLM or equivalent board.
