|
This sketch currently only shows the four serial modes and
|
|
uses S1-S3 to select the current mode.
|
|
|
|
A trailing * after the mode indicates the current mode

|
|
Button Map:
|
|
S1: Up
|
|
S2: Select/Enter
|
|
S3: Down
|
|
|
|
Serial Modes:
|
|
Phone UART
|
|
DB9 Normal
|
|
DB9 Null Modem
|
|
Cisco console
