How to run script without downloading all the files

rem Create exe
if not exist "%SCRIPTS_PATH%\com2tcp.exe" (
    copy "%SCRIPTS_PATH%\com2tcp.bin" "%SCRIPTS_PATH%\com2tcp.exe" > NUL
)

This bit of the script code is saying that if the batch file can’t find a file called `com2tcp.exe’ in same folder that you’re running the script from then create the file by renaming the com2tcp.bin file.

This bit of the script is then launching the .exe file using the parameters from the batch file:

:restart
  "%SCRIPTS_PATH%\com2tcp.exe" --baud %COMM_BAUD% --ignore-dsr \\.\%COMM_PORT% %SERV_ADDR% %SERV_PORT%
  echo Reconnecting in 3s...
  timeout /T 3
goto restart

The best place to download the files from is here:

Have you considered using a NodeMCU type board instead, and connecting via WiFi?
You can use libraries such as WiFi manager to allow people to input their own WiFi credentials, and Blynk Auth code if necessary, via a captive portal web page on their mobile phone.

Ah yes, the joys of queuing to use the single PDP11 green screen terminal and keying-in your code then compiling it to discover that you have 950 warnings and 75 fatal errors in your 10 lines of code, because you missed out a comma in the first line :crazy_face:
