Are you trying to call from the WiModem232 to your S-100? DSR never has the connection state no matter what you have it set to, per the Hayes standard. It is typically used to tell the terminal if it is in command mode or not.
The receiving side can only know about a connection by either monitoring the communications and watching for a "CONNECT" message or by monitoring the DCD line. After a connection occurs, only the state of the DCD line can tell the modem that the connection is active or has been lost.
