We have a remote access PC card that came with our original system (we started over 10 years ago with ACS R1 and upgraded to R3 back then with the Remote Access PC card which has a 1998 sticker on it). We just upgraded to ACS R8. This remote access card does not seem to work with the ACS R8 (when I try to connect remotely, it makes modem buzzing noises instead of the normal modem squealing noises and will not connect). Is this card compatible with ACS R8 or can I update the software on it to make it work?
