This certainly isn't true.  I run SLIP on a generic 2 port serial card
with 16550As and an APT 8 port card, both using FAS, and SLIP works with
no problems.  So, ISC's stock ASY driver isn't required.  This is with
ISC 2.2 and their TCP/IP 1.2.

Has Interactive shipped an update to their TCP/IP that supports PPP?
