Well, it is immediately obvious that they've used a simplistic algorithm: I suspect that it would be No Big Deal to talk to a blazer in whatever manner of multi-line implementation we choose... In response to Jon's previous message, I concur that a multi-link PPP implementation would be preferable. However, given that I am not much of a kernel hack, and that there is code that already works (and just needs to be ported/hacked) for SLIP, I think I would prefer to tackle the job that looks mildly intimidating, rather than the job that looks hopelessly impossible. grin :-) ...
