8.4 REMOTE COMMUNICATION INTERFACE
Hayes-compatible command string to the modem located at the PC. The LPS-O does not send any configura-
tion commands to its modem. Both the relay modem and the PC modem must be uniquely configured to permit
logging into and communicating with the relay using LPSO-Link software.
The required configuration settings are presented as changes to the factory-default configuration settings for a
Hayes V-Series 2400 SmartModem. The default settings are listed below.

E1 Q0
L2 V1
M1 W0
N1 X4
Other "Hayes-compatible" modems may implement a subset of the full Hayes command set. It is the responsi-
bility of the customer to determine the exact commands accepted by a particular modem. The proper syntax for
entering the Hayes-compatible commands (sometimes referred to as the AT command set) is not described
here. Refer to the modem manual for an explanation of this syntax.
The PC modem must be configured for intelligent (command recognition enabled) operation. For the Hayes V-
Series 2400 SmartModem, this setting is made with an internal jumper. The default settings listed in Section
8.4.2: MODEM CONNECTIONS AND SETTINGS are valid for LPSO-Link. The configuration settings critical to
the operation of LPSO-Link are sent to the modem from the software:

ATE0L0Q0S7=60V0X4Y0
These commands are explained in Table 8–4: COMMAND SEQUENCE SENT BY LPSO-Link TO MODEM.
