On powerup, the CLKin and DATAin are tied via a 74LS240 or something to CLKout and DATAout. Each are also tied directly to the appropriate serial ports on the user port. The only problem I had was in breaking the connection. you need to ensure you break the connection while the lines are at rest. Breaking during a transmission would cause a lot of problems.
