This program opens a TCP/IP port. When a connection is made to that port (e.g. with telnet) it forwards all data to the serial port and vice versa. This example only exports a raw socket connection. The next example below gives the client much more control over the remote serial port...
This module encapsulates the access for the serial port. It provides backends for Python running on Windows, Linux, BSD (possibly any POSIX compliant system), Jython and IronPython (.NET and Mono). The module named "serial" automatically selects the appropriate backend. It is released under a ...

When the module communicates with the cloud over the MQTT protocol, in order to distinguish different data frames, the module's serial port adopts a simple data frame for external protocol: <topic_id>,<msg_len>,<msg_data>. Example messages Upstream message: "1,6,abcedf" Downstream message...
If the command from the second example above is started at 11:30pm (system time), the program will capture data for one hour butwill produce two output files; one with the date and time it was started and another with the date and time that the program first outputs data after the sys...
