2.10.7. Tube

The tube is a memory-mapped register. If you write a printable character to it, the character appears on the console. It allows you to check that writes are taking place to a specified location in memory.

You can change the address at which the Tube is mapped. This is controlled by an entry in peripherals.ami:

{Default_Tube=Tube
Range:Base=0x0d800020
}

This is the default address.
