   Regarding this Centronics parallel discussion, can anyone
mail me the handshaking scheme on the STROBE L and ACK L lines?
It appears to be full-interlock, but I have no documentation
to explain.

   Also, the BUSY and SELECT lines seem to have the same
function: in my (bad) documentation, BUSY is "high when data
cannot be received" and SELECT is "high when printer is
ready to receive data." I take it that when either of these
lines is high, the printer will ignore (not ACK) a byte
strobed to it.

   Can anyone elucidate? Thanks!
