Is it technically possible to have a user level implementation of SLIP under 4.3 BSD and its derivatives? I mean, having something like a daemon reading and writing from/to a tty and then sending/receiving from an IP socket? I understand this is not going to be as efficient as the in-kernel implementation, but it makes it much easier to experiment with various algorithms for packet compression. --mt (Manolis Tsangaris)

I'd be interested in anyone who has slip or slfp user level code that works with this. From the README file: This is the tunnel driver for routing IP packets over other networks. In particular it can be used for rfc877 encapsualtion of IP packets over X.25 - but the kernel level driver just delivers IP packets to listening processes. The approximate steps for installation of the driver are as follows.
