My grandson has an imac. He also has a PC notebook with an EVDO connection card in the PCMCIA slot. He wants to be able to pair the 2 machines via bluetooth and use dialup networking (DUN) on the imac to cause the PC to connect to the internet and thereby connect the imac to the internet. He and I haven't been able to setup DUN on the imac. In the PC world, this is known as "tethering." Any help will be greatly appreciated.
