Rose Porter PO-4S - Switch

The Porter versatile, code-activated switch allows one computer to send a code to select one of several devices. The Porter can be configured to match the type of equipment that you have. You don't need a PC to use the switch or to configure it. The Porter is easy-to-install, it uses commonly available cables and works with any device with serial or parallel ports. Receive buffers accept data on all ports simultaneously. This data can then be read from the master port one at a time. The Porter transmits from buffers on all ports simultaneously. Null destination command allows disconnect from all ports. Format command allows a port's protocol to be re-configured by command, useful for modem communication. The "clear buffer" command purges all data in a port's buffer. The broadcast feature allows you to send data simultaneously on all ports. The Porter is one of the best code activated switches on the market.
