tn3270 uses the standard UNIX file termcap to determine whether or not
a particular terminal type has these features. An administrator must make
termcap accessible to tn3270 and ensure that the terminals using tn3270
have terminal types listed in this file (see Configuration Checklist on page
A-226).
Print Screen and Transparent Mode
The Remote Annex tn3270 has two features not available with the
Berkeley version of tn3270 on which it is based. These are:
• The IBM print-screen function.
• The ability to turn transparent mode on or off.
Transparent mode is useful for running file transfer programs such as
Kermit. The command you use to turn transparent mode on or off depends
on the IBM host. This feature requires no special configuration.
The print-screen feature lets you dump a screen from the IBM host session
to a printer. To do this, enter the Remote Annex key sequence that is
mapped to the IBM LPRT key.
The network administrator must configure the print-screen feature. This
includes mapping a Remote Annex key sequence to the IBM LPRT key
(see Terminal Emulation on page A-218 and Configuration Checklist on
page A-226). It also involves setting the na/admin port parameters
printer_name and printer_host. These parameters have user-level
equivalents, printer and printhost, that can be set using the CLI stty
command. Table C-72 describes both sets of parameters.
