Hi, We are running small ISP. Recently I tried to get Caller ID of PPP dial-up users. As I had read from mgetty documentation the #CID=1 modem command (with nomder of rings set = 2) switch on this mode. Howevery it does not work for me, though this Acer modem support it. Where can I find more info concerning this subject. TIA, Eugene Sevinian ---------------------------- CRD, YerPhI, 375036, Armenia URL: http://crdlx5.yerphi.am/ Phone: 374-2-344873
