I have an X86 box with ROS 4.6 that I'd like to configure as a dial-in server. I had purchase and installed a 4 port serial card in the router. The motherboard itself has one serial port, but when I check /system/ports only the four on the serial card seem to be recognized, and one port is for console. Can I remove the console port and config all four as dial in ports. I had configured a PPP server on the router, but don't know what else to do. I had seen a document somewhere here, but I can't seem to find it again. Can someone point me in the right direction. Thanks.
