Has anybody tried debugging io-net components through serial line?Here is
what i am doing.(Ser1 of target is connected to Ser1 of the host machine).
Since i need to debug a io-net component i cannot use the other method of
using a TCP port in place of serial line
Any help is greatly appreciated…

I’ve done this successfully. Not really sure
what the problem is here. Do your baud rates
match at either end.

Yes…the baud rates are 57600 on both sides(pdebug man page recommends
it).By the way sometimes i do happen to get Remote debugging using /dev/ser1
message.But after the next command (for e.g., info pidlist) The errors start
occuring and it never recovers…Should i be running anything else on the
target machine?
Thanks

Sorry to bother again guys…
I really need to find a solution for this problem.Can somebody tell
me if anything is missing from the following steps to achieve Remote
debugging over a serial line
What could i be doing wrong in this?
Sreekanth
ps: I have tried changing the baud rates at both the places to 115200 but
didn’t seem to help.

I don’t think there is anything wrong with your method. It
sounds like a problem at the serial level. You might have
more luck posting in public.os, public.devtools.

It works fine for me at 57600.

I am able to connect to the target machine using qtalk at 115200 baud but
for Gdb i am stuck with 9600. Any ideas?

Not really. You should probably try public.qnxrtp.devtools.
