b) Processing a Key Sequence
To execute a series of keystrokes that have been recorded:
- Press <Alt Gr><F5> to set the Process mode,
- Press the recorded function key,
- The key sequence is processed.
Example:
1 - Press <Alt Gr><F5> to set the Process mode. The 3270 status line is
set in reverse video mode and the following information is displayed
(the 12 boxes are the 12 function keys, a solid box means that data is
recorded):
EXEC    17/21
2 - Press the recorded function key (from <F1> to <F12>). The 3270 status
line is set in normal mode and the following information is displayed (the
'P' symbol indicates the Process mode). The key sequence is
processed:
P 17/21
Note: during the process mode, the input is inhibited.
7.3 - 3270 PRINTER
Auxiliary ports (2 serial and 1 parallel) and logical ports (USB and TCP) are
provided by the AX3000. These ports are independently controlled so multiple
printers can be attached to the AX3000.
These printers can be controlled by one of two protocols:
- Prt3270: a printer controlled by this service is seen as a standard
spooled system printer device.
- LPD: this service (RFCs 1048 and related) is provided as a standard
feature by major operating systems (Unix/Linux, NT, etc.). The main
benefit of this protocol is an LPD printer can be shared by different
operating systems.
This chapter describes only the Prt3270 protocol.
