10 .Nd "driver for Comtrol RocketPort Intelligent Serial Port Cards"
14 This driver provides a kernel device driver for the
19 These boards provide 8, 16, or 32 high-speed serial ports
20 while requiring only 68 bytes of I/O space for all 8, 16,
21 or 32 ports, and do not require an interrupt channel.
22 This driver supports up to four
26 boards in one machine simultaneously.
27 If you are using four 32 port
29 boards, you can put as many as 128 intelligent serial ports
34 driver supports the following speeds: 50, 75, 110, 134, 150,
35 200, 300, 600, 1200, 1800, 2400, 4800, 9600, 19200, 38400, 7200,
36 14400, 57600, 76800, 115200, and 230400.

54 card requires a 68-byte contiguous block of I/O addresses,
55 starting at one of the following:
56 0x100h, 0x140h, 0x180h, 0x200h, 0x240h, 0x280h, 0x300h, 0x340h,
58 The second, third, and fourth
61 64-byte contiguous block of I/O addresses, starting at one of the
63 The I/O address range used by any of the
65 cards must not conflict with any other cards in the system,
69 The starting range of the I/O ports used by each card
70 must match with the I/O address specified in the kernel
75 uses 68 I/O addresses, if the first card is
76 set to use an I/O block starting at 0x100,
77 it will occupy the I/O ports between 0x100 and 0x143.
78 This means that the second, third, or fourth
80 board may not use the block of addresses starting at 0x140,
81 since the first three I/O addresses of that range
82 are used by the first board.
83 This is an important point to keep in mind.
85 The configuration of the
87 cards is done via the set of 8 DIP switches,

99 DIP switches 7 and 8 are unused, and must be left on.
101 DIP switches 6 and 5 identify the card number of each
104 The first card installed in the system must have its DIP switches set
105 as card number one; the second card installed in the system must have
106 its DIP switches set as card number two; and so on.
108 the factory, DIP switches 6 and 5 are both on by default, indicating
109 that this is the first card installed on the system:

126 cards installed in a system,
127 the second, third and fourth
130 also be set to the I/O address range used by the first
133 all cards must have these DIP switches set identically
134 for proper operation.
135 As shipped from the factory, DIP switch 4 is on,
136 and switches 3, 2, and 1 are off by default,
137 indicating an I/O address range used by the first
138 card which starts at 0x180 and extends to 0x1C3.

169 machine, and the flow control is very heavily exercised, on rare occasions
170 a character will get dropped.
