I have a software that requires a dialup connection from my Macbook to the hospital I work out of. The more recent versions of this software (it is called Meditech by Cambridge) don't work with any G5 Mac, so I have been hoping that I could connect under Parallels. No luck so far. I have not been able to get the Apple USB external modem to connect and I bought a Trendnet USB external modem and tried to install this in my Windows desktop without any success. I have read through many threads on this subject and am still looking for a solution. Any help would be appreciated.
