To replace my rockwell/riptide combo modem due to phone problems we installed an Intel HAM faxmodem which causes my AOL to hang/lock or connects at a very low speed (12000 bps sometimes) and doesn't get past the "connection speed .." portion of the AOL connection in other words I get kicked off or couldn't establish connection at all with the network - NOTE: this is at my friend's place(he owns the PC) - when he brought the PC to me to check out what's wrong I connected the PC to my phone line and the AOL connected at optimal speed with no sign of delay. I connected several and AOL never had any problems connection. I told him the modem is ok and he took it back to his place and voila still the same problem. We tried the other AOL access numbers but the problem remains. Do modems have limitations or incompatibility with certain types of phonelines, if there is more than one type? I know some modems behave differently if there is voicemail, which causes the line to pause before a dialtone is present. Can you please advise?
