The last time I purchased a modem, it was for an ISA slot. So, as you can imagine, that was quite a long time ago. Now, I have a computer with an ECS K7SEM (microATX) motherboard. It has a modem in an AMR slot, but it does not work. I've tried numerous times to get it to work, but I always get a message that the modem is not responding. The AMR type slot was new to me with this motherboard. If I get a different modem, I'm wondering whether I should try another AMR type, or would it be better/safer to go with a PCI modem? Since this is a microATX board, I only have two PCI slots. Would be nice to keep them available for other uses, but will use one of the for a modem if necessary. I'm just not sure whether there's a problem with the AMR slot on this board or whether the modem is simply bad. I've always used the LAN connection for Internet access but may be selling the computer to someone who would want a modem in it.
