dev/ttyUSB0 Downloading and configuring DOSBoxĪs I mentioned earlier, we have to use MS-DOS to program the radios. If you’re using Linux, you can read the syslog or enter ls /dev/ttyUSB* (if you’re using a USB adapter, if you use an internal port it might start with ttyS) in your terminal: ls /dev/ttyUSB* If you’re using Windows you might want to do that in the device manager (Win + R → devmgmt.msc) – serial devices start with COM and have a number at the end, e.g. Software setup Finding the serial portįind out the serial port. When connected to the 9V battery, the red LED on the RIB-less cable should be on. From left to right: RS232-USB, 9V battery, GP300 with RIB-less cable You have to remove the GP300-battery and use the RIB-less “cable”. This includes the 9V battery with the VCC/GND wires, the DB9 serial port and the GP300 itself. That’s the easy part: Connect everything.
You can buy those “adapters” on eBay pretty cheap. Well, or just receiving if you don’t own a license. Yes, you got that right: Today, we’re going to program the old (but reliable) Motorola Radius GP300 – released more than 20 years ago around 1998, it’s older than me! Programming the radios isn’t that easy as they have to be programmed using a special MS-DOS software and using a “RIB-less” cable via RS232.
