LZ: RS-232 & RS-422 Standards



  Can anyone point me in the right direction to find out more about the 
RS-232 & RS-422 protocols?  I'm trying to connect the $4 link to my MAC, 
and though I have found info from Apple on the Mac serial-port pinout, my 
best efforts have turned up nothing on the actual protocol (Mac uses 
RS-422 while PCs and most other systems use RS-232).


  Any help would be greatly appreciated.
