Prepare files to be sent

A file can be sent to the port by file command - after the command is entered, any key will open a dialogue box for selection of the file to be sent.

Any files can be sent to COM port this way.

A file can be transmitted by entering file command and then selecting the file to be sent in dialogue box.

One should remember that the bigger a file is the longer it will take to transmit it.

When a file is being transmitted, performance of any other tasks is not possible.
