Switch #4

Unix UUCP Spoofing

(Asynchronous Mode/Leased Line/Dial-Up)

The modem can be configured for use with Unix equipment which employs ACK flow control to monitor data integrity. The modem can do "UUCP spoofing", where the modem is able to generate ACKs at the DTE interface. Data then is transmitted more time-efficiently, because the delay of waiting for data to be received then waiting for the ACK to be returned at the remote end, is eliminated. Placing DIP-Switch #4 in the DOWN position enables UUCP spoofing.

UUCP Spoofing Enabled	=	Switch #4 DOWN
UUCP Spoofing Disabled	=	Switch #4 UP
Factory Default Setting	=	UP

Switch #5

Enable/Disable Auto-Answer - "Ans"

(Asynchronous Mode/Synchronous Mode/Dial-Up)

In some originate-only applications, you may wish to disable the modem’s automatic answering capabilities. This may be true if you have a telephone set attached to a modem and wish to receive voice calls that you yourself would answer instead of the modem. Place DIP-Switch #5 in the UP position to enable Auto-Answer. Place DIP-Switch #5 in the DOWN position to disable Auto-Answer.

Auto-Answer Enabled	=	Switch #5 UP
Auto-Answer Disabled	=	Switch #5 DOWN
(Factory Default Setting	=	UP)

Switch #5

Originate/Answer Mode

(Asynchronous/Synchronous Mode/Leased Line)

The modem functions in either Originate mode or Answer mode. Place DIP-Switch #5 in the DOWN position to enable Originate mode. Place DIP-Switch #5 in the UP position to enable Answer mode.

Originate Mode Enabled	=	Switch #5 DOWN
Answer Mode Enabled	=	Switch #5 UP
(Factory Default Setting	=	UP)

Switch #6

Maximum Throughput Setting

(Asynchronous Mode/Leased Line/Dial-Up)

Some applications require you to dial into services with maximum throughput on, and other applications where maximum throughput must be off (i.e., service not supporting error correction, or the V.42 handshake interferes with logon sequence). DIP-Switch #6 is used for switching between these two modes. This DIP-Switch controls three important parameters (error correction, speed conversion and serial port speed), which in effect enables or disables maximum throughput.

Maximum Throughput Enabled	=	Switch #6 UP
Maximum Throughput Disabled =		Switch #6 DOWN
Factory Default Setting	=	UP
