Just an update to the programming nightmare. I have a few radios that boot up super fast and I think are saying V202.
Anyhow I found that I needed to switch to 9600 baud to read or program these radios. Note this changes the options that you can program to the radio. Don't give up. The software versions need to be the correct one for the radio.

I found in the 5300 HELP section that Johnson suggest using a KEYSPAN USA-19HS USB to 9 pin RS-232 converter. I also had several other USB converters tha did not work, however the KEYSPAN does and I actually found mine on EBAY-that fixed the read write error. The other thing, in PREFENCE you can set the delay times higher which will fix other compatibility issues created by "lag time" between the computer, software and hardware latency.

One other thing on the software, Under TOOLS open PREFERENCES one the next page, click on OTHER under SERIAL COMMUNICATIONS increase the SEND/GET DELAY time. That makes the software "wait" for a response from the hardware-it worked on mine!
