We have considered a number of methods and wondered whether anyone has other ideas or suggestions. (By the way, this is on VMS). Potential solutions include: 1. The user that initiates communication becomes the controlling job for all processes in the link. His job will connect mailboxes to the other processes and make sure that I/O reaches every terminal. This method would not allow the controlling user to leave the link without some messy work! 2. The user that initiates will open a mailbox to some hibernating process or will cause some process to come alive that will serve as a channel until nobody uses it anymore. This seems like a win, although we would rather avoid spawning a number of jobs of this nature. We are most interested in efficiency. Thanks for suggestions! -Michael Adler P.S. Please reply to me. I am not on the list.
