We implement a simple control software and data plotter for a device called the Wanderer. It was also known by its Finnish translation Kulkuri. The device is a battery-operated and portable sensor device manufactured around 1991 by Elektrobit/Extrabit. The only unit I've seen measures ambient temperature and vibration as a function of time. The device came with a disk containing a control program meant for Windows 2 and 3. The interesting parts of the original software are reimplemented here.

I haven't seen any technical documentation for this device and I'm not sure if it even exists at this point. I reverse engineered the serial protocol. There are probably some mistakes and misinterpretations.

So far I've only gotten the device to work with Windows 10 and using a motherboard provided RS232 serial port. No luck with a few different USB-RS232 adapters on Windows or Linux...
