AFINET.SYS

This file driver is called the IBM OS/2 TCP/IP Stack Protocol Layer: Transport protocol device driver for the AF_INET socket type.

AFINET.SYS is the transport protocol device driver for the AF_INET socket type. AFINET.SYS is essentially TCP/IP code. It is compliant with NDIS version 2.0.1; any MAC driver written to that specification should work with the stack. SLIP, PPP, X25, and SNAlink use a special interface in this driver to their respective hardware.
