.SH "KEYS"
.PP
.TP 16n
In session, the following key sequences are intercepted as tio commands:
.IP "\fBctrl-t ?"
List available key commands
.IP "\fBctrl-t i"
Show settings information (baudrate, databits, etc.)
.IP "\fBctrl-t q"
Quit
.IP "\fBctrl-t s"
Show statistics (total number of bytes transmitted/received)
.IP "\fBctrl-t t"
Send ctrl-t key code

.SH "EXAMPLES"
.TP
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.
