$DT OK*xx
Parameters updated successfully
$DT ERR*xx
An error response
Notes:
For the query option, the return value of $DT <rate>*xx requires different parsing than the
normal $DT message format. The application should check if a comma is present in the $DT
string, and, if so, assume it is the standard date/time format. If no comma is present and the
value is a number, then the value is the rate being returned in response to the $DT ? query.
