Writing a Batch File for MS-DOS Serial Port Communication

[gimini75]

Hello

Can anyone help me please, I want to write a batch file in MS-DOS to:

Communicate with the serial port, send data to the serial port from a specified file and for a respond to come back from the driver that first command being done and now ready for next line of data to be send it through the serial port to a stepper driver.


Thanks for your help

That's going to be tricky to do with batch
The normal tool for doing this sort of thing is expect http://expect.nist.gov/

Hello, writing a batch file for MS-DOS serial port communication can be a useful tool for automating data transfer and communication between devices. To begin, you will need to have a basic understanding of MS-DOS and how to use the serial port commands.

First, you will need to specify the serial port you want to communicate with using the "mode" command. This will set the baud rate, parity, and other settings for the serial port.

Next, you can use the "echo" command to send data from a specified file to the serial port. Make sure to include the appropriate commands or characters to indicate the end of the data transmission.

To receive a response from the driver, you can use the "echo" command again to send a command or prompt to the driver. The driver should then send a response back to the computer, which can be captured using the "set /p" command. This will store the response in a variable that can be used in the batch file.

Once the first command has been completed and a response has been received, you can use the "goto" command to move on to the next line of data to be sent to the driver.

Overall, writing a batch file for MS-DOS serial port communication requires a good understanding of the serial port commands and how to use them effectively. With some practice and experimentation, you can create a batch file that efficiently communicates with a stepper driver and automates your data transfer process. Best of luck with your project.
