Hi,
Did anyone tried to use serial qnet by using devn-fd.so .
We tried but not succeded .
Any sucession ?
thank in advance

Depends on what version of QNX your are running.
Try “use /lib/dll/devn-fd.so” see if there is a “ahdlc” option, if so,
you need to load devn-fd.so with that option to allow packet
based protocol (like QNET) riding on it.

I am using RTP 6.2 NC
use /lib/dll/devn-fd.so dos’nt show “ahdlc” option.In which wersion it
should show this option ?
Probably 6.2.1NC then. “use /lib/dll/devn-fd.so” on my machine looks like
this:
$ use /lib/dll/devn-fd.so
devn-fd.so FD interface driver.
Syntax:
io-net -d fd [option[,option …]] … &
Options (to override autodetected defaults):
fd=device Device to read/write packet data.
mac=XXXXXXXXXXXX MAC address of the controller. No default.
wait Wait for the device to be inserted.
verbose Be verbose.
ahdlc read/write packet data in AHDLC frame format
Examples:
io-net -d fd fd=/dev/ser1,mac=0023456789AB,ahdlc -p tcpip
ifconfig en0 10.184

Does AHDLC support multipoint links ? (I suspect not).
If not, devn-fd.so seems the proper tool to use for multinode
links, if ahdlc is not used.
We want to implement devn-fd.so over a multinode radio modem, the
fact that devn-fd.so implements a MAC address makes this feasible,
but I am concerned that devn-fd.so doesn’t work without ahdlc.
Why does devn-fd.so require ahdlc ? or does it ?

I am not sure what you are asking.
AHDLC simply add the concept of “packet”(or “frame”) into devn-fd.so,
so that data transfered by devn-fd.so is not just a “byte stream”.
I don’t think it have anything to do with “multipoint link” or “multinode
links”.

OK, I had a very hard time finding any description of what ahdlc is (lots
of references to it, but no descriptions).
Thanks

I have tested devn-fd.so on 6.2.1 NC,it is functioning with AHDLC
option. But if your mac adress starts with “0” character,ping okey,
tcpip services like ftp,telnet etc. not functioning . I thing it is a
bug on devn-fd.so.

It’s Asynchronous High-level Data Link Control. Basically, it is what PPP
used to form a “ppp frame”.
