Question

Can we control the serial port by writing a batch file through the cmd prompt in windows? and how if we can?

Answer 1

Tricky one, this. There are two problems to be solved, initialising the port and writing to it. The second part is easy with the redirection symbol > with a line like



type txtfile.txt > com1



which will redirect the output of the type command from the screen to a serial port. The real problem is initialising the serial port with the correct transmission rate, start/stop bits etc to agree with the device at the other end. There is no way of doing this from a command prompt. I used to do it from a C or assembly language program, which you would have to write and incorporate in your batch file.



You may find it easier to use a terminal program like Hyperterminal to communicate with your serial port.

Answer 2

once you place CMD in a batch document, it won't easily open a clean window, it is going to easily teach you a clean command instantaneous in the comparable window. as quickly as you're finished with the consultation, you could proceed on with something of your batch document with the help of typing "go out". in case you prefer to open a clean window and have the batch document wait until eventually that's closed, do something like this: @echo off initiate /wait "Temp CMD instantaneous" cmd /ok "cls && echo type 'go out' to end this consultation." echo you have exited the command document.

it was controlled under " interlink " may not be in newer versions .
