[plug] PPP Connection having problems

[Andrew Oakeley]

Hi,

I've been biting my tongue, you obviously have your reasons, but I cannot
hold on any longer.... wouldn't 2 NICS and a crossover cable be a better
faster solution?

I have always found null modem/direct cable connection to be rather painful.
