I think the problem is mysql. I download mysql for qnx from internet,
and don´t works, and i can´t connect to internet.
I read help in qnx and i try to repair with io-net but don´t works. I
don´t know to do.
Also my connection broke when i install patch A for Qnx, i had to
reinstall qnx.
Excuseme my english, i´m spanish.
Thx.
