2.5.2 SER2.receive(timeout)
This command receives a string from serial port ASC1 waiting for it until timeout is expired. Return
value will be the first string received no matter of how long the timeout is. Input parameter timeout is a
Python integer, which is measured in 1/10s, and represents the maximum time of waiting for the string
from the serial port ASC1.
Return value is a Python string which is an empty string if timeout expired without any data received
otherwise is the string containing data received.
Example:
a = SER2.receive(15)
receives a string from serial port ASC1 handling, waiting for it for 1.5 s, assigning return value to a.

This command receives a string from serial port ASC1 without waiting for it. It has no input parameter.
