Comtrol QNX 4.xx - Manual (Page 2)

Note: By default, the install command looks in the
diskette drive for the driver files.
5. Load the driver using the Loading the Driver
discussion.
Loading the Driver
Before loading the driver, make sure that you have
installed the RocketPort ISA or PCI cards. If you are
installing an ISA card, it may be necessary to change
the
I/O address (default is 180) setting. Use the Hardware
Reference Card or the readme file for hardware
installation procedures.
To load the driver, issue the following command line
from either the command prompt or from the /etc/
config/sysinit file. See the Quickstart discussion for
sample command lines.
If you are installing RocketPort PCI cards, they are
detected before any of the RocketPort ISA cards and you
do not need to specify I/O addresses or IRQs for
RocketPort PCI cards. The system determines the order
of the PCI cards.
Note: If you type 'use Dev##.rckt' you will get
command line help.

The following is a table of load option parameters.
Quickstart
The following illustrates some sample installations.
Note: You may receive Error 23 File Table Overflow
message if the QNX Device Manager (Dev)
statement does not have a large enough value for
the -n option in the sysinit file to accommodate the
number of ports.
• Starts Dev32.rckt with PCI cards only.
Dev32.rckt &
• Starts Dev32.rckt for one RocketPort ISA card with
the base I/O address of 180h using IRQ11. If any PCI
boards are installed, they are detected and installed
first.
Dev32.rckt 180,11 &
• Starts Dev32.rckt for 2 RocketPort ISA cards with
the first using a base I/O address at 180h with IRQ
11, the second with a base I/O address at 100h using
IRQ 15, both 1200 baud. If any PCI boards are
installed, they are detected and installed.
Dev32.rckt -b 1200 180,11 100,15 &
Table 1. Commands
Command Description
[path] The path to the Comtrol driver files. Optionally,
you may either add the directory to your binary
path or copy the Comtrol driver files (Dev##.rckt)
to your /bin directory.
Dev##.rckt Where ## is the specific driver; that is:
* Dev32.rckt is the 32-bit version of the driver
(QNX 4.23 and higher)
* Dev16.rckt is the 16-bit version of the driver
(QNX 4.22 and below)
[options] Represents any combination of the parameters
listed in Table 2.
[addr]
(ISA only) Represents the I/O base address (hex) of each
RocketPort ISA board you are installing. This is not
required for RocketPort PCI boards.
[irq]
(ISA only) Represents the software interrupt you want to use
with the RocketPort ISA board (default is 15).
RocketPort ISA cards cannot share interrupts
(IRQs). If you are running in poll mode, you do not
need to specify any IRQs.
Once loaded, the driver creates devices for each
board in the /dev directory by the name of rckt#,
unless otherwise specified by the -N name option;
where # is 1 through the number of ports on the
card.
Table 2. Driver Load Options
Options Description
-p Poll mode (Interrupt default) - 137 Tx polls/sec
and 100 Rx polls/sec. If IRQs are specified along
with this option, the IRQs are ignored.
-b number Defines initial baud rate (default 9600).
-C number Size of canonical input buffer (default 256).
-d Sets DSR on initially (default).
-D Sets DSR off initially.
-e Sets options to “edit” mode.
-E Sets options to “raw” mode (default).
-f Enables and locks hardware flow control (default).
-F Disables hardware flow control.
-h number Defines high-water mark for system input buffer
flow control (default 3/4 point of input buffer).
-I number Size of raw system input buffer (default 2,048).
-l number Defines low-water mark for system input buffer
flow control (default 1/4 point of input buffer).
-m Disables modem carrier processing (HUP).
-M Enables modem processing (HUP) (default).
-N name Prefix to register (default “rckt”).
-O number Size of system output buffer (default 2,048).
-r Sets RTS on initially (default).
-R Sets RTS off initially.
-s Enables output flow control (ohflow) split, CTS
only required (default).
-S Disables output flow control (ohflow). CTS and
DSR required.
-x Enables and locks software flow control.
-X Disables software flow control (default).
