Sending AT commands to COM port via Windows 10 command line?

Question

Command line

All AT commands work through the HyperTerminal program. All OK. The modem makes calls to the specified number. But here through cmd everything is deaf. When sending the command "echo ATD + 48 *********; >> COM9" zero response (modem on the 9th com port).
Any ideas what is the problem?
I want to create a .bat file which will contain a script of several commands. Only first you need the modem to accept AT commands through the command line.

PuTty can connect via a COM port, it includes a command line utility that can send commands from a file. Try this bundle instead of hyperterminal.
