It is need to start ppp server.
What utility in QNX 6 (like mgetty in Linux) listen the COM port and start the pppd when connection between two modems is starting?
How to config PPP server?
This is a more difficult task than you might think. I’m afraid that a search on “modem” here on OpenQNX is the best I can recommend right now.
