Modems connected to the Small System should be set as follows:
• Carrier Detect (CD): Active if carrier detected on incoming call
• Clear to Send (CTS): Normal operation or forced active
• Hardware and software: Disabled flow control
The ports on the Small System are disabled if devices connected to the ports
generate additional "garbage" characters. For this reason, do not use modems
in the following modes:
• Loopback
• Auto Echo
• Self Test
Note: The Serial Data Interface (SDI) ports are designed for use with
"dumb" modems. "Intelligent" modems can be used. Make sure that the
modems do not enter into modes of operation that send additional
characters to the system.
