 Print one or more AT command values from Inverter.
 Use all known AT commands, if no one is given, e.g.:
 .../inverter-connect$ ./cli.py print-at-commands
 Or specify one or more AT-commands, e.g.:
 .../inverter-connect$ ./cli.py print-at-commands WEBVER .../inverter-connect$ ./cli.py
 print-at-commands WEBVER WEBU
 e.g.: Set NTP server, enable NTP and check the values:
 .../inverter-connect$ ./cli.py print-at-commands NTPSER=192.168.1.1 NTPEN=on NTPSER NTPEN
 wait a while and request the current date time:
