However I have not run across a PLC that can initate AT commands, causing your modem to autodail out. You may need a modem that will initate a dial via a seperate input. Check this link for a modem that will dial out: http://web3.automationdirect.com/adc/Shopping/Catalog/Communication_Products/Modems/MDM-TEL
