Abstract

With each card of a certain "Z" computer product capable of emulating up to four of the seven possible sessions present on each port of the host system, it becomes apparent that there will not be enough addresses for each user to have all the sessions he may want on a dedicated basis. A user could not even make full use of two "Z" cards if each had to be configured on a static basis. This definition provides a dynamic method of starting, stopping and changing the configuration of emulated workstation sessions, without requiring the termination of other sessions. (Image Omitted) One very popular method of attaching workstations to the IBM S/36 and S/38 is via twinax cable using the T1P1 protocol. Using this protocol, up to seven workstations can be concurrently active on each port of the host system.
