With the BLACK BOX? Code-Operated Matrix Switch, any port can select 
any other port. Mix and match PCs and peripherals in any combination 
for maximum flexibility. This flexible switching eliminates the need 
for a master port. Any of the switch’s ports can communicate with any
other port. Also, any two ports can communicate simultaneously. For 
example, you can use the switch to connect two PCs to either a serial
printer, a modem, or a host. As one PC sends data to the serial 
printer, the other PC can send data to either the modem or the host.
