Send the provided string after opening and configuring the serial port.
The init string is sent exactly as if it was input at the terminal, and
thus obeys the \f[B]\-\-omap\f[] output mapping, the \f[B]\-\-echo\f[]
local\-echo setting, and the \f[B]\-emap\f[] local\-echo mapping.
This feature is useful, for example, if the serial device needs some
special magic strings to start responding.
Use $(echo \-e ...) or xxd to generate special characters like a CR or
binary data.
Note, that the initial string is not sent if \f[B]\-\-noinit\f[] is set.
Use \f[B]echo(1)\f[] or \f[B]xxd(1)\f[] to generate special characters
like a CR or binary data.

Exit picocom after remaining idle for the specified time (in
milliseconds).
Picocom is considered idle if: Nothing is read (received) from the
serial port, AND there is nothing to write (send) to the serial port,
AND nothing is read from the terminal.
If \f[B]\-\-exit\-after\f[] is set to zero, then picocom exits after
opening and configuring the serial port, after sending the init string
(if any, see option \f[B]\-\-initstring\f[]), and imediatelly when it
becomes idle.
When exiting with \f[B]\-\-exit\-after\f[], picocom observes the
\f[B]\-\-noreset\f[] setting as usual.
(Default: not set).
