• An out-of-range value for a particular option is specified In the
above example, if the fourth value in the option string is
undefined or out-of-range for option 13 in a certain modem (and
no other error conditions apply), options 10 through 12 would be
changed as specified in the command message. The next option to
be changed would be option 13. The modem would then detect
that the value is undefined or out-of-range for that option, stop
execution of the command, and return an
INVPV013
message
Options 10 through 12 would still be changed as commanded;
options 13 and 14 would be unchanged.
