3.1.2 The 3964R Communication Program
The general functionality of the program MVI46_3964R.RSS is as follows:
Send jobs to a CP:
ƒ Transfer the job data to the MVI46-S3964R.
ƒ Acknowledgement from the MVI46-S3964R regarding validity of the job data.
ƒ Depending on the type of send job the transfer of the user data from/to the
MVI46-S3964R/SLC processor takes place.
ƒ Acknowledgement from the MVI46-S3964R regarding
successful/unsuccessful completion of the send job.
Receive jobs from a CP:
ƒ Depending on the type of receive job the transfer of the user data from/to the
MVI46-S3964R/SLC processor takes place. The header data generated from
the MVI46-S3964R will be added automatically. The MVI46-S3964R needs
no extra job data from the SLC processor for receive jobs, it will be triggered
through the STX character sent from the CP to establish the communication.
ƒ Acknowledgement from the MVI46-S3964R regarding
successful/unsuccessful completion of the receive job.
During the processes described above additional status/error messages may be
transferred from the MVI46-S3964R to the SLC processor (refer to Module
Status Data Table (page 60)). Refer to Error Processing for more information.
