Using the CLI Commands

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 Check List on page

The Model 5390 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 Model 5390 key sequence that is mapped to the IBM LPRT key.

The network administrator must conﬁgure the print-screen feature. This includes mapping the Model

5390 key sequence to the IBM LPRT key (see Terminal Emulation on page C3-83 and Conﬁguration

Check List on page C3-89). 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 C3-35 describes both sets of parameters.
