DOJO PROJECT: SIMPLE CHAT CLIENT

This example shows how to write a program that uses the DOJO protocol with a direct connection, that is, not mediated by specific hardware. To work, you need to connect the retro computer via serial according to the instructions on the dedicated web site. Alternatively, you can use an appropriately configured emulator.
