## The BACKSPACE key and how to delete typos
|
||||
|
||||
The Apple 1 didn't have a typical "backspace" key as we are use to today, due to the way the video display worked it couldn't move the cursor backward to erase characters. So instead it used a "rubout" character, which is the underscore character (__). This character signifies that the input buffer has been moved backwards one character (eg. "PRN__INT" would be received by the Apple 1 as "PRINT").

It takes a little getting used to but you'll soon get the hang of it.

## The Apple 1 only understands UPPERCASE characters
|
||||
|
||||
If you're using the PS/2 input you don't need to be worried about this, as we automatically UPPERCASE all typed characters so WozMon can understand what you are typing.
|
||||
|
||||
However if you are using the UART and a serial terminal you will need to remember to turn on your CAPSLOCK, otherwise nothing will respond as you might expect.
|
||||
|
||||
## Serial Setup
|
||||
|
||||
Depending on the baords you can use serial to communicate with the Apple1, some boards require a toggle to be set to select between PS/2 input and UART input. The UART by default will be set to 115200 (8/N/1).
