In my old days, it always worked to connect RTS,CTS and DTR on each side of the RS232 cable.
You loose the handshake capability, but you can send data over;
A few hours of debugging might save you from minutes of reading the documentation! :D

Sounds familiar, but there is only RTS and DSR at the device, so it should not matter leaving them open.
When doing stuff like that, people should have at least a Multimeter and a simple logic analyzer. Otherwise you end up lost.
