I’ve connected a PCI serial Card to my QNX computer. Can anybody briefly
describe how to setup the serial ports and interrupts in the sysinit file?
Also, I would greatly appreciate it, if someone can provide sample code to
activate the interrupt and read from the serial port.
Thanks,
Shashank
You can use the Dev.ser driver with 16550 compatible serial cards.
example: Dev.ser 3f8,4
Use the “show_pci -vv” command to get the ioport and irq for the device.
(see Utility Reference for details)
To read and write to the device you can use open(),read(),write (see Library
Reference for details).
i.e.
fd= open("/dev/ser1", O_RDWR);
len = read(fs, buf, BUF_SIZE);

We are already using COM1(3F8) and COM2(2f8) for something else.
I’d like to use COM3(3E8) and COM4(2E8) and share interrupt 5 between these
2 ports. For now, I am thinking of using the Lava PCI serial borad and the
manual says that I can have the 2 ports share an interrupt.
Thanks for your previous reply,

When i connected this PNP card to my PC , it assigns interrupt 11 to the two
devices on this card. And there is an interrupt conflict with the Display
device? I have no way to control the interrupt assignment.
Should I try to change the slot to see if it makes a difference?

I don’t think any of our graphics drivers ever use the interrupt, or
enable it. So, ineterrupt 11 is usally safe.

There are usually settings in the BIOS to assign IRQs to PCI slots. Doing
this may help to resolve conflicts.

Till you don’t use ISA (PC/104) display adapter there is no conflict.
PCI devices can share interrupts not only being placed on the same board
but being anywhere on PCI bus in a system. No matter what kind of PCI
device. So, you can have video card, USB host adapters, multiserial
boards, etc. all using the same interrupt line. It isn’t a great idea to
connect everything to single interrupt line while there are spare
interrupts lines in system, but it should work and there is no conflict.
I have no way to control the interrupt assignment.
Sometimes these settings are somewhere in BIOS Setup. Interrupt
assigment for PCI devices is done by BIOS during POST.
Should I try to change the slot to see if it makes a difference?
Usually it makes difference. But you don’t need to. Sharing interrupt
with display is OK. Sharing interrupt with network card could be much
worse. Because NIC produces a lot of interrupts and they are time
critical for the NIC driver, as well as the serial card is a great
producer of interrupts and again the serial driver has to handle
interrupt before the FIFO overflows. For the 16C550 UART based board,
the FIFO is only 16 bytes long.
In a conclusion,
(To print settings of “Com1”)
(To print settings of fifth serial port).

We have code written for Lava’s ISA boards that read data from the ports
using dev_read(). We’d like to try this out on the PCI board. Since we
needed to arm proxies we didnt use read(). Will dev_read work just like
read()?
I appreciate your suggestions

When my controller boots up it comes up with the following:
Dev ID Vend Id Dev No IRq
0110 1407 17 11 Simple Comm contrl
0111 1407 17 11 Simple Comm contrl.
So i presume it has detected the Lava card and assigned it interrupt 11.
However, if i run the show_pci command , it doesnt show me this card.
Whereas the VGA which is using 11 is displayed in the output of the
show_pci command. I am using a PNP frame grabber that uses interrupt 10 and
that is also displaybed by show_pci.
Am i missing something?

I was just using 3f8,4 as an example, simply substitute the
appropriate
values for your device.
i.e. Dev.ser 3e8,5 2e8,5Regards,

You can use the Dev.ser driver with 16550 compatible serial
cards.
example: Dev.ser 3f8,4Use the “show_pci -vv” command to get the ioport and irq
for
the
device.
(see Utility Reference for details)To read and write to the device you can use
open(),read(),write
(see
Library
Reference for details).i.e.
fd= open("/dev/ser1", O_RDWR);
len = read(fs, buf, BUF_SIZE);Regards,

Try moving the card to another PCI slot.

The ‘show_pci’ utility will only show pci devices.
ISA devices will not be listed.Regards,

When my controller boots up it comes up with the following:Dev ID Vend Id Dev No IRq
0110 1407 17 11 Simple Comm contrl
0111 1407 17 11 Simple Comm contrl.So i presume it has detected the Lava card and assigned it
interrupt
11.
However, if i run the show_pci command , it doesnt show me this
card.
Whereas the VGA which is using 11 is displayed in the output of
the
show_pci command. I am using a PNP frame grabber that uses
interrupt
10
and
that is also displaybed by show_pci.Am i missing something?
Thanks

I tried changing it to a different slot but it still wouldnt work. Is there
a web-site where i can get the latest version of show_pci or a similar
utility?

There is source code for show_pci somewhere; I have an older copy of it
myself. You could compile and run it under the debugger, to see where the -v
option is crashing. Might give you some insight.
