Need help - PPP MGR

I got a beta version of QNX RTOS Ver4

it came with the file (file size 22782 bytes
loaded in /x86/lib/dll/ for dialup networking.

unfortunately, a file with the similar name is also loaded in
/dev/socket with file size shown as zero bytes.

When I tried mount the ppp mgr from terminal, i get response
“unable mount, unknown special file or file sys”

Unable to delete the file in /dev/socket directory, evevn when logged
in as “root”

Any solution for this problem.

I am unable to use qnx for my internet connectivity.
