I was wondering how I could configure my 2521 with 4 serial, two of which are (A/S), to connect to the internet via a modem? I would like to know what type of modem to buy, what type of cables/connectors will be needed to connect the modem to the (A/S) serial ports. I searched for other modems but I can never seem to find anything, that I "know" would be able to hook into my router. Any help would be greatly appreciated!
