On windows 7 the mode function has these parameters: https://technet.microsoft.com/de-de/library/cc732236(v=ws.10).aspx#BKMK_1
You have to set the attributes that meets your system specification.

After that you can use the com port as follows:
1) Create a data file, that contains what you want to send, and
2) then copy the file content to the com device of your choice

So the resulting batch file should be similar to this:

Code: Select all

:: the next line must be edited to your requirements
mode com<M>[:] [baud=<B>] [parity=<P>] [data=<D>] [stop=<S>] [to={on|off}] [xon={on|off}]

:: prepare file data.bin
<nul >"data.bin" set /P "=4"

:: copy to console device (edit com<M> to meet your requirements)
 copy /b "data.bin" /b com<M> /b
