Use the same interface method as specified for AppleShare PC 1.2. This is
documented in the APDA documentation for both AppleShare PC and the LocalTalk
PC Card.
The reason the LocalTalk PC Card developer notes are relevant is that even
though AppleShare PC 2.0 runs over multiple physical media, the API remains the
same.
There is one important additional step that must be taken. Included with
AppleShare PC 2.0 is a program called COMPAT.COM that installs a TSR (Terminate
and Stay Resident) process. This process ensures compatibility between
programs using the AppleShare PC 1.2 interface and AppleShare PC 2.0, and the
program should be run at system startup.
