rp - driver for Comtrol RocketPort Intelligent Serial Port Cards
For ISA cards, you must specify the port address in /boot/device.hints hint.rp.0.at=isa hint.rp.0.port=0x100
The driver supports the following speeds: 50, 75, 110, 134, 150, 200, 300, 600, 1200, 1800, 2400, 4800, 9600, 19200, 38400, 7200, 14400, 57600, 76800, 115200, and 230400. (You must use termios(4), rather than the old style ioctl interface to use non-traditional speeds.)
An open on the driver will block until carrier is present, unless O_NONBLOCK or CLOCAL is set.
Since the first RocketPort uses 68 I/O addresses, if the first card is set to use an I/O block starting at 0x100, it will occupy the I/O ports between 0x100 and 0x143. This means that the second, third, or fourth RocketPort board may not use the block of addresses starting at 0x140, since the first three I/O addresses of that range are used by the first board. This is an important point to keep in mind.
If you have two ISA cards, one installed at 0x100 and the second installed at 0x180, then you should add the following to /boot/device.hints
hint.rp.0.at="isa"
hint.rp.0.port="0x100"
hint.rp.1.at="isa"
hint.rp.1.port="0x180"
The configuration of the RocketPort cards is done via the set of 8 DIP switches, labeled SW1 on the RocketPort card:
+-------------------------------+ | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | +-------+-------+---------------+ | Unused| Card | I/O Port Block| +-------------------------------+
DIP switches 7 and 8 are unused, and must be left on.
DIP switches 6 and 5 identify the card number of each RocketPort card. The first card installed in the system must have its DIP switches set as card number one; the second card installed in the system must have its DIP switches set as card number two; and so on. As shipped from the factory, DIP switches 6 and 5 are both on by default, indicating that this is the first card installed on the system:
DIP Switches 6 5 =================== On On First Card On Off Second Card Off On Third Card Off Off Fourth Card
DIP switches 4, 3, 2, and 1 indicate the I/O address range used by the first RocketPort card. If there are more than one RocketPort cards installed in a system, the second, third and fourth RocketPort cards must also be set to the I/O address range used by the first RocketPort card; all cards must have these DIP switches set identically for proper operation. As shipped from the factory, DIP switch 4 is on, and switches 3, 2, and 1 are off by default, indicating an I/O address range used by the first card which starts at 0x180 and extends to 0x1C3.
DIP Switches I/O Address Range 4 3 2 1 Used by the First Card ===================================== On Off On Off 100-143 On Off Off On 140-183 On Off Off Off 180-1C3 Off On On Off 200-243 Off On Off On 240-283 Off On Off Off 280-2C3 Off Off On Off 300-343 Off Off Off On 340-383 Off Off Off Off 380-3C3
