Attached is the DZ11 pinout in ASCII art, require 92 columns, so please
widen your xterms or resize your VTs to 132 columns. Those on TTYs are
safe.. :-)


Please certify that this is correct.

Pin = BERG's pin
Sig = EIA/RS232C signal
Ch  = Serial line channels: 0-7 
Example:
Ch0 TX:  pin 21
Ch0 RX:  pin 19
Ch0 SG:  pin 22
Ch0 RI:  pin 20
Ch0 DTR: pin 1
Ch0 DCD: pin 2
Note: Take notice of aesthetic layout of pins per channel: 1 square block of 4x4 and a column of 1x2
