The integrated Code-Operated Switch, RS-232, 4-port is an asynchronous RS-232 switch with four subordinate ports and one master port that enables you to switch serial devices with codes.

There's no unintended triggering with this switch - no matter what data you're sending. You can set each port individually as DTE or DCE. That's handy for switching among modems and printers. And your connection is secure. Once a connection is made, other ports are locked out. For extra control, there's a hardware-handshake lead in each direction in case a device needs it.
