      CXY08 Switch Settings

========================================================================

   The CXY08 (M3119) is a Q-bus 8-port asynchronous serial adapter with
full modem control.

========================================================================

   The 10-position DIP switch sets the mode and CSR address.

      Mode (switch 1) open = DHU11 mode (normal).

      CSR (switches 2 through 10): open = 0, closed = 1.

------------------------------------------------------------------------

   General:

CSR bit: 21 20 19 18 17 16 15 14 13 12 11 10  9  8  7  6  5  4  3  2  1  0

Switch:                              2  3  4  5  6  7  8  9 10

Binary:   1  1  1  1  1  1  1  1  1  s  s  s  s  s  s  s  s  s  0  0  0  0
             `-----'  `-----'  `-----'  `-----'  `-----'  `-----'  `-----'
Octal:    1     7        7       6,7      0-7      0-7    0,2,4,6     0

------------------------------------------------------------------------

   Example, 17760440:


CSR bit: 21 20 19 18 17 16 15 14 13 12 11 10  9  8  7  6  5  4  3  2  1  0

Switch:                              2  3  4  5  6  7  8  9 10
                                     o  o  o  o  c  o  o  c  o

Binary:   1  1  1  1  1  1  1  1  1  0  0  0  0  1  0  0  1  0  0  0  0  0
             `-----'  `-----'  `-----'  `-----'  `-----'  `-----'  `-----'
Octal:    1     7        7        6        0        4        4        0

========================================================================

   The 8-position switch sets the interrupt vector.

      Unknown (switches 1 and 2): 1 always closed, 2 always open.
      Vector (switches 3 through 8): open = 0, closed = 1.

------------------------------------------------------------------------

   General:

Vector bit:  8  7  6  5  4  3  2  1  0

Switch:      3  4  5  6  7  8

Binary:      s  s  s  s  s  s  0  0  0
             `-----'  `-----'  `-----'
Octal:         0-7      0-7       0

------------------------------------------------------------------------

   Example, 310:

Vector bit:  8  7  6  5  4  3  2  1  0

Switch:      3  4  5  6  7  8
             o  c  c  o  o  c

Binary:      0  1  1  0  0  1  0  0  0
             `-----'  `-----'  `-----'
Octal:          3        1        0

========================================================================

   In SYSGEN CONFIGURE for a CXY08, specify device "DHV11".
