I don't think they use STAC at all on NT. The protocol is not CCP either. I suspect both the protocol they use and the compression method are MS proprietary....until NT5.0 (rumor has it). >> Ascend Max-HP T1/PRI S/N: 6122652 Software +5.0Ap13+ > > There was a problem in anything before 5.0Ap16, I had to deal with >a customer with this kind of setup, he would connect fine, but after 5-10 >mins no data would go thru.

Why ? I was able to connect in much less time - I disabled the compression option in WIN95 DUN - relying instead on modem compression....
