11.Sh SYNOPSIS
12.Cd "device rp"
13.Cd "device rp0 at isa? port 0x180"
14.Sh DESCRIPTION
15This driver provides a kernel device driver for the
16.Tn RocketPort
17and
18.Tn RocketPort RA
19serial boards.
20These boards provide 8, 16, or 32 high-speed serial ports
21while requiring only 68 bytes of I/O space for all 8, 16,
--- 41 unchanged lines hidden (view full) ---
63above address ranges.
64The I/O address range used by any of the
65.Tn RocketPort
66cards must not conflict with any other cards in the system,
67including other
68.Tn RocketPort
69cards.
70The starting range of the I/O ports used by each card
71must match with the I/O address specified in the kernel
72configuration file.
73.Pp
74Since the first
75.Tn RocketPort
76uses 68 I/O addresses, if the first card is
77set to use an I/O block starting at 0x100,
78it will occupy the I/O ports between 0x100 and 0x143.
79This means that the second, third, or fourth
80.Tn RocketPort
81board may not use the block of addresses starting at 0x140,
82since the first three I/O addresses of that range
83are used by the first board.
84This is an important point to keep in mind.
85.Pp
86The configuration of the
87.Tn RocketPort
88cards is done via the set of 8 DIP switches,
89labeled SW1 on the
90.Tn RocketPort
91card:
