There are numerous ways to accomplish getting the PID for an established network connection in AIX and Linux using tools like ss or more popular lsof. In my situation, the system I was working on did not have ss or lsof, so I used netstat and rmsock.
If I know I have an established connection to a remote host 192.168.9.150, I can use netstat to narrow down and obtain the PCB/ADDR using the following command.
~ # netstat -naA|grep 192.168.9.150

Had an issue with dialout on an AIX system this morning. Problem resolved, but I learned a pretty handy little command for testing dial-out (I didn't have a buttset with me).
Using cu -n -d -l tty2, I can dial-out to my cellphone to help in troubleshooting the problem.
# cu -n -d -l tty2
Please enter the number: xxxxxxxxxx

Instead of using Shift+Backspace to backspace on an AIX terminal, you can use the following setting in the .profile:
stty erase '^?'
Save the file and logout and back into the AIX terminal and Backspace should work now.
An easy way to get a quick overview of system performance on an AIX server is to use the topas command.
