Steps

When you are not using the RESET lead, cap or tape it to isolate it electrically. This prevents it from grounding and inadvertently resetting the modem.

TO POWER OFF THE MODEM

1.If you are running a HyperTerminal session, disconnect from the modem by clicking HyperTerminal’s Disconnect button.

2.Disconnect or close all other applications accessing the modem’s serial ports (such as another HyperTerminal session or the Globalstar User Terminal Program Support Tool [UTPST]). It is not necessary to physically unplug the Modem Interface cable or Diagnostic cable from the modem.
