MR> I did like you said. I dialled David's BBS with a dial string of

MR> How do you interpret that? 

I presume the V32 is a typo, but apart from that, it appears that S15=128
has disabled LAPM altogether, so if you use that value, I suggest you
disable MNP5 with &K0 as well.  What connect string does S15=136 give?
