program to allow access to all types of devices that provide serial
consoles. It could also prove useful in many other similar tasks.
In effect, picocom is not an "emulator" per-se. It is a simple program
that opens, configures, manages a serial port (tty device) and its
settings, and connects to it the terminal emulator you are, most
likely, already using (the terminal window application, xterm, rxvt,
system console, etc).
When picocom starts it opens the tty (serial port) given as its
non-option argument. Unless the **--noinit** option is given, it
configures the port to the settings specified by the option-arguments

: Write hex. Picococm prompts the user for a string of hexadecimal
values. Values can be entered with or without delimeters
(separators). The hexadecimal values are translated to binary and
sent to the port, exactly as if input at the terminal (i.e. the
**--omap**, **--echo** and **--emap** options are
observed). Example: The following sends the characters "ABCD" to
the port.
