I know very little about Mac computers, but a Mac owning friend of mine is attempting, with the advice from a MAC dealer, to use an external 56k modem (Cardinal brand name) designed, according to the enclosed instructions ,to be used with a PC. Macs are not mentioned. Are PC modems useable with macs? If yes then what would have to be configured in the computer to optimize its settings to match with the new modem. He's having problems and I am unable to help him.
Thanx.
