Allow user to select which ANSI color code to use to colorize the tio text. To successfully set the color the color code must be in the range 0..255. If color code is negative tio will print all available ANSI colors. The default color is changed to bold white to make tio defaults usable for most users, including color blind users.

Typical use is without options. For example:
|
|
|
|
tio /dev/ttyUSB0
|
|
.TP
|
|
Which corresponds to the commonly used options:
|
|
|
|
tio \-b 115200 \-d 8 \-f none \-s 1 \-p none /dev/ttyUSB0
|
|
.TP

It is recommended to connect serial tty devices by ID. For example:
|
|
|
|
tio /dev/serial/by\-id/usb\-FTDI_TTL232R-3V3_FTGQVXBL\-if00\-port0
|
|
.PP
|
|
Using serial devices by ID ensures that tio automatically reconnects to the
|
|
correct serial device if the device is disconnected and then reconnected.
