Comscope has two modes of operation. Input from terminal (stdin) and input
from external application. Comscope closes at end of file, so file
redirection and and pipes can be used with comscope. For more sophisticated
scripting you can use ``-e`` parameter to supply command to execute.
This command is passed to shell. Standart input and output are then
redirected to serial port and communication is displayed on the terminal.

Comscope displays all communication going over serial port, differentiated
by color (unless explicitly disabled). Color codes are as follows:

green
  printable data sent to serial port
cyan
  non-printable data sent to serial port, as escape sequences
red
  printable data received from serial port
magenta
  non-printable data received from serial port, as escape sequences
