VT5250 Connectivity
VT5250 is a twinax emulator that uses TCP/IP to connect to a Twinax Server. The
example below shows how VT5250 connects to the internal Twinax Server in each
iCON, giving the impression of a normal, self-contained, 5250 Twinax Display unit.

With Session Sharing configured, multiple VT5250 clients can connect to a Twinax
Server. This way there is both a local and a remote display of the same Twinax session.
Keys typed on one keyboard show up on all displays, so there is no guessing as to
whether someone else is currently entering a command. Configurable keyboard
arbitration will lock out other keyboards while a command is entered. Keyboard
Lockout Override will allow a privileged user to take control of the keyboard if
necessary.
In the following example, the Windows PC has a VT5250 connection to both iCONs,
allowing console control of two LPARs from a single desktop. So the SysAdmin can
enter console commands from his office, while the IT staff still have local consoles in
the computer room.
