MS-DOS command to change com port?

Answer 1

Use the "change port" command (without the quotes, of course) to change the port you're deciding to map to somewhere else.

First, to display the current com port mappings, you can use change port / query

Then, to change a port, type change [old com port]=[new com port]

NOTE: Change the text in the brackets to the actual com port, making sure to use keyword "COM," again without the quotes, and in the example, without the brackets

Here's an example:

change port COM2=COM4

Finally, to delete a COM port listing, use the following format:

change port /d [COM PORT]

Here's an example of deleting a COM port listing:

change port /d COM8

Hope this helps!
