Asynchronous Communications Element

Serial Experiments Lain’s Lain holding a serial cable wondering about serial line settings

Today I tested UARTs I got for my (hopefully) upcoming m68k based computer. It’s a couple of TI TL16C550A. Decided to use Arduino because it’s a 5V device so I didn’t need level-shifters because I am rapidly running out of those… :/

Screenshot of my desktop. The left monitor in portrait has datasheet for the UART open; the right monitor has Arduino code, logic analyzer and 3 minicom windows.

Breadboard with a real mess of wires connecting 2 ACE(UARTs) to an Arduino Uno, logic analyzer and 2 serial to USB converters
