Provide IP-to-PPP services
io-net ... -p pppmgr ...
The npm-pppmgr.so shared object provides IP-to-PPP services. If you use pppd, you'll need to load npm-pppmgr.so.
When npm-pppmgr.so is loaded, you can get information related to the amount of data transmitted and received, and the number of transmission or receiving errors. For example:
cat /dev/socket/pppmgr ppp0: ----- Bytes Received: 58990 Bytes Sent: 57735 Packets Received: 95 Packets Sent: 79 Receive Errors: 0 Send Errors: 0
io-net -p pppmgr
