link calls, status information calls and reply solicitation calls.
I/O parameters on ECI calls

returned to the user application following an ECI call.
Program link calls
An ECI request to call a program on a CICS server results in a program link call to
attach the CICS mirror transaction
to run the server program.
Status information calls
Status information calls retrieve status information about
the connection between the client and server systems.
