A.2 Remote Communication to the COM210
To remotely communicate with the COM210, program the datalogger to
initiate a call to it using a program similar to the Example Program 1.* After
this program runs once, the modem is now programmed and the actual
program one wants to run may now be downloaded to the datalogger.
*Please note that this program requires that the option code for an RF modem
be used instead of the normal phone modem option.
