Hi Bob,
Fortunately I have an AS400 commtrace of the working
device from another project(working nicely with the
AS400). When I compare the two of them, it is clear
that the difference lies in the INIT-SELF. At startup
time, my program will do an init-self WRITE invite.
Apparently the device did not respond to the init-self
invitation. I haven't got the commtrace from OS/390, I
will try to get one to compare as well.
Currently we can setup the 4701 device to send
init-self and it is now able to communicate.
The plan was to hook-up 200 4701 devices already
running in production at different branches. It is
unlikely to go down and setup all 200 devices manually
to send INIT-SELF so that it can talk to AS400. It
will be very efficient if we can just tweak at the
AS400 site.
