A week ago I posted a question on getting SLIP working. I got an answer. I
also got a lot of questions like 'Yeah, I've got the same problem. Can you
send me any answers you get...'. This and the fact that my rmailfile got
completely screwed up this morning (and I lost the adresses of the people
requesting an answer) is the reason I post here. (I hope c.o.l.admin is the
best group to post to. Where is c.o.l.networking? :-))
Original question (abreviated):

Notice also that you should set your 'mtu' not too high. I use 256. Otherwise
you may get effects like: 'I can get the first few Kbytes and then the link
