Build Your Own Z80: TESTS II

UART Terminal Echo Test:

This test is at the top of the webpage.

In this test, we'll configure the 16550 UART for 1200bps and 8N1 byte framing. The system has been tested reliably to 115,200bps but it's always smart to start with a slower speed during initial testing.

UART Terminal String and Echo Test:

This test is at the bottom of the webpage.

We'll output a string to the terminal, then echo every key the user presses.
