2.17.2 Establish Transparent Mode with VISONIK DCS
After starting KERMIT at the PC, a "Transparent Mode" must be established with the
partner VISONIK DCS. This means that, from the operator point-of-view, the PC looks
as if it is a directly connected VISONIK DCS terminal from which the system can be
operated.
This mode is established by input of "CON" (abbreviation for "Connect") at the PC.
KERMIT acknowledges the action of this software link to VISONIK DCS, as follows:
Kermit-MS>CON
[Connecting to host, type Control-] C to return to PC]
_
Esc chr: ^], Port: 2, Speed: 2400, Parity:None, Echo: Rem, Type ^]? for Help
"Connecting to host" means here that VISONIK DCS is the host system.
If necessary, return to the PC's KERMIT program by breaking off Transparent Mode
with the VISONIK DCS.
2.17.3 Start VISONIK DCS "KERMIT" Program (SERVER)
After setting up Transparent Mode with VISONIK DCS it is now possible to carry out a
dialogue as if the PC were a normal operating terminal.
Initial access to Function KER is opened through input of Crtl/P and by entering the
abbreviation "KER". After terminating this input with <CR>, KERMIT now runs in
VISONIK DCS, the SERVER comes into operation and is acknowledged by:
ctrl/P
T6 12:34:56 Function =PNT : KER
Kermit server running on VISONIK host
# N3
Esc chr: ^], Port: 2, Speed: 2400, Parity:None, Echo: Rem, Type ^]? for Help
If the dialogue is not immediately continued by terminating Transparent Mode, the PC
displays character sequence "# N3" at the screen's left side after 75 seconds. This has
no immediate effect on KERMIT operation. Only after a timeout of 1 minute in VISONIK
is KERMIT stopped. This can be restarted again with Ctrl/P as described above.
