Implement this using two semaphores, one for ICWCONN1, and one for everything else (ICW_ELSE)
|
|
On startup, each component set its semaphore, then checks what other components are running.
|
|
|
|
Conn1: check for ICWCONN1, ICW_ELSE
|
|
Isignup: check for ICW_ELSE
|
|
Isignup .ins: no checks
|
|
ICWCONN2: no checks
|
|
Inetwiz: Check for ICWCONN1, ICW_ELSE
