For an external modem, the RTS and CTS pins are connected directly (not crossed).
External modems are connected to a BMXNOR0200H module by a serial direct cable using an RS232 physical link. BMXNOR0200H module works with many commercially available modems.
The illustration below shows how a modem is connected to a slave BMXNOR0200H module configured with PPP:
NOTE: In case of a PPPoE configuration, connect the modem on the Ethernet port of the BMXNOR0200H module.
