QNX 6, Neither ISA nor PCI Modems recognized, Help!

I installed QNX v6 and so far I really like it. Unfortunately, I cannot
fully explore QNX because I an unable to get either one of two modems to
work with it :frowning: I have an ISA slotted USR 56K PnP Voice FAX modem. It is
not a “winmodem”. After many disappointing attempts to get it working, I
replaced the modem with another USR model, a PCI slotted 56K PnP modem (not
a winmodem either). QNX doesn’t seem to recognize the PCI slot modem either
:frowning: Anyone have any suggestions on how I can get a modem working with QNX?

Thanks

I believe that some folks have gotten the USR PCI modems to work (in QNX 4)
by using show_pci to get the base address of the registers and passing those
parameters to Dev.ser. I’m not sure how to do that in QNX 6 but hopefully
you can do the same thing. The problem is that the base address of those
registers are going to be very high addresses (i.e. not standard).

Good luck.

Bill, Thanks for the assistance. I’m still new to QNX, how do I use sho_pci
and Dev.ser to add my modem? I reverted back to my trusty ISA slotted USR
modem, is there anything I can do so that I can continue using this modem
instead of the pci one?

Thanks

As long as it isn’t a Win Modem you are ok. If the modem is
a PnP modem, you can use isapnp to set its I/O port and IRQ.
If it is not a PnP modem, it will probably have dip
switches on the board. Once you know the I/O port and IRQ
for the modem, you pass this to Dev.ser when you start it.
By default it will check for a serial port at 3f8 and 2f8
with IRQ’s 4 and 3 respectively. If your modem is set to
one of these positions, you don’t have to do anything.

Bill and Mitchell,

Strange… When I open a terminal window and type “show_pci” or “isapnp”,
I get an error message that says the command is not found :frowning: Any ideas?

Thanks

Hi Mitch

I think he want to use it with RTP. I’m still stuck developing with QNX 4.
So I’m pretty sure that the equivalent commands exist in RTP. I just don’t
know what they are.

Does anyone know the RTP equivalent commands?

Also, if the modem is a PCI as I think he said in the original post then I
think that the show_pci and passing the address found is the better way to
go than the isapnp route. But I guessing there too.

Not strange at all, you are using QNX 6. Something I must have missed
before. QNX 6 should have discovered your modem and set it up as a
/dev/ser# device. Since it didn’t, it must be having some kind of
trouble.

I had a similar problem with my system at home. It seemed that QNX 6 was only
looking at the first serial port. Try creating an rc.local file in your /etc/rc.d
directory and add the following:

!#/bin/sh
devc-ser8250 -u2 2f8,3

Then chmod the file to make it executable, reboot and see if it sees your modem.
Hope this helps.

Finally… A modem that works!

The US Robotics 56K FaxModem PCI (Model 5610A) works fine :slight_smile:
