This invalid message can be returned when a block of options is being changed. The conditions for this invalid response are as follows:

•An undefined option number is specified. In the above example, if option 12 is undefined for a certain modem (and no other error conditions apply) options 10 and 11 would be changed as specified in the command message. The next option to be changed would be option 12. The modem would detect that this is an undefined option, stop execution of the command, and return an INVPV012 message. Options 10 and 11 would still be changed as commanded; options 13 and 14 would be unchanged.
