How to read Data over Serial using Com Ports

[@jyvben1520]

for windows, the program used was Putty, this also works on linux, where the port(s) are /dev/tty.... e.g. ttyACM0, ttyUSB0 the linux user (not root) might need to be part of the dialout group, do the following in a terminal (need sudo rights) sudo adduser $USER dialout (where $USER points to the current logged in active user, or replace it with your logon name )

You might need to check the indicator settings to ensure it is set to continuous and that the correct baud rate is selected. If the settings are correct, you may need a null modem cable, as pins 2 and 3 are swapped. However, if you are already using a null modem cable, try switching to a regular (non-null modem) cable. Alternatively, you can purchase a DB9 null modem adapter (male to female). The female end plugs into the DB9 male connector of the cable, which then connects to the indicator. This will also swap pins 2 and 3. Pin 2 is TX (Transmit), and Pin 3 is RX (Receive) on the DB9 connector. These items are readily available on Amazon. If none of this works, there might be an issue with the internal board. Finding the correct cables and null modem adapters can be tricky. Thanks, Anthony

I've tried this but it just doesn't work for me. It connects but doesn't give me any data.
