SDI-12 Extended Command Support
SDI12Recorder() sends any string enclosed in quotation marks in the Command
parameter. If the command string is a non-standard SDI-12 command, any
response is captured into the variable assigned to the
Destination parameter, so
long as that variable is declared As String. CRBasic example Use of an SDI-12
Extended Command
(p. 189)
shows appropriate code for sending an extended SDI-
12 command and receiving the response. The extended command feature has no
built-in provision for responding with follow-up commands. However, the
program can be coded to parse the response and issue subsequent SDI-12
commands based on a programmer customized evaluation of the response. For
more information on parsing strings, see Input Programming Basics
(p. 211).
