AGILE 5250 OPTIMA User’s Guide and ReferencePage 2-6
4. TRNSPRNT. Transparent. This is used only for diagnostic purposes.
5. HEX DUMP. Hex dump mode will cause the 5250 OPTIMA to
print all data it receives as 16 hexadecimal bytes per line on the left
column of a page, accompanied in the right column by the 16 ASCII
characters they represent. SCS/DCA commands are represented by a
backslash (\) character. Refer to Chapter 5  Maintenance &
Troubleshooting for a printout of a sample Hex dump.
To select a mode, use the arrow keys to move through the menu to the
MODE: selection for the twinax device, use d and f to display the mode
name, then press ENTER. For example:
OPTIMA: CONFIG:TWINAX1: MODE=IBM EMUL
Changing a twinax ports mode, like changing its address, causes the
OPTIMA to end communication on that address, change the mode, then
reestablish communication on the address, unless the address is currently
in use. The twinax address must timeout before the OPTIMA will end
communication on the address. (See the section Timeout later in this
chapter for more information on timeouts.)
Data Routing
Each input channel is user-configurable to allow output to any
combination of output ports. When data is received from an input port
(twinax or alternate host), the OPTIMA looks at the output ports in order
of priority, searching for an output port that is acceptable to the input
ports configuration. The first acceptable output port that is not in use by
another input port is acquired and used. If all configuration-allowable
output ports are currently in use, the input port must wait in a queue for its
turn.
The output ports have a predefined priority:
1. PO  PARALLEL OUT PRINTER (if active)
2. S1  SERIAL I/O PORT 1 (if active and configured for output)
3. S0  SERIAL I/O PORT 0 (if active and configured for output 
typically used for input)
The OUT TO: selection in the menu under TWINAX: allows the user to
choose those output devices to which each input device will send data. To
select the output devices, use the arrow keys to move through the menu to
the OUT TO: selection for the twinax port, use d and f to display the
output devices, then press ENTER. For example:
