The following are solutions to problems that can occur when communicating over APPC:
Automatic transaction initiation against a Client daemon terminal
does not work
Different products provide different APPC implementations for handling inbound attaches. Therefore for the Client daemon using IBM® Communications Server, Microsoft® Host Integration Server, and IBM Personal Communications, you must predefine the CRSR attach program to relay the information to the Client daemon. This is necessary to enable the CICS® server to perform automatic transaction initiation (ATI) against the Client daemon terminals.
