Step		Action
1	Connect the shelf modem to the PC and verify that it is in working condition as described in the preceding
	section, “Management Station External Modem.”
2	Use a communications program to send the following initialization string to the modem:
	AT&F
	This string resets the modem to its original factory configuration and clears any previous programming
	that can conflict with the communication between the modem and the EMU.
3	Send the following configuration string to the modem:
	ATE0Q1S0=1&K0Y0&W0
	This string configures the modem to operate properly with the EMU. The commands in this configuration
	string are as follows:
	AT	The command prefix indicating an AT command
	E0	Do not echo input characters
	Q1	Do not return result codes
	S0=1	Answer the phone after the first ring
	&K0	Disable flow control
	Y0	Use profile 0 as the power-up configuration
	&W0	Store current configuration as profile 0
	Note: The shelf modem does not respond with an "OK" when you enter the above string. This
	string disables all response codes and echo capability in the modem. The response codes
	are not used by the EMU.
	When the modem is properly configured, the Auto Answer (AA) lamp on the modem panel
	lights, indicating that the modem is waiting for the phone to ring to answer an incoming call
	from the management station PC.
