I'm going to need to use dialup internet on my MBP fairly soon (but only temporarily, thankfully). I know I need to get an Expresscard/34 dialup modem, but can I get *any* Expresscard/34 modem? And what about the software to do the actual phone dialling? Is that still built into OS X even though MBPs don't have a phone jack on them any more? Any advice appreciated!
