Hey guys,

After several years my old HP laptop broke and I bought several toshiba 2515cds and a IBM 380d thinkpad thinking they would work. All have the same pentium 1 and 16 mb ram that my HP had but all of them have trouble accessing comport. I am using a genuine rib with homemade cables. I am trying to reprogram my gr300 that I previously programmed with the old HP. I had to replace the harddrives and reinstall windows 98.

ANY help please?

Check in the bios and turn off any IR ports, as they can conflict with the serial port. It's a common issue in the IBM's at least.

Tried this but whenever I try to read the radio, in the upper left corner of the GM300 program screen, I get "Accessing Serial Port" and it just continues to try to find port. As far as I know I have all IR ports disabled on both the IBM and Toshiba. All are doing the same thing.

Have you verified the RSS isn't set for COM2 maybe?

The com port is set to com 1. I also went into the device manager and made sure that is were the serial port was.

If you can run Win95, run hyper terminal and short pins 2 and 3 of the serial port together and see if you have a loopback OK. If you can only do DOS, put a volt meter or scope on the com port output and copy a large file to the com port <copy example.text com1> and see if there is anything being sent. If that's OK then try the reverse <copy com1 con> wiggle the com port input (another PC, signal gen 1kHz +/- 3V or more, or just touch a wire on it sometimes works) and see if you get random characters on the screen. If all that checks out then check your cables.

I know my cables work because I have used them to read the radio with the broke computer (the case is cracked and fragile but still operational) but I will try your suggestion. Will hyper terminal work in windows 98 that is all I have. Thanks for the suggestions and I will let you all know what happens.

Win98 is better!
