TTYPE - Terminal Type

This Natural profile parameter allows you to specify the terminal type used - in TP environments in which this information is not supplied automatically - so that Natural can activate the appropriate converter routine for attribute sequences to operate that type of terminal.

Possible settings 1-4 characters The setting specified with the TTYPE parameter must be defined as a valid terminal device type in the NTDVCE macro of the NATCONFG module, see Configuration Tables - Module NATCONFG.

Dynamic specification yes  
Specification within session yes The TTYPE parameter has the same function as the terminal command %T=.

If you use the TTYPE parameter, it is no longer necessary to execute a program containing a SET CONTROL 'T=...' statement at the start of the session in order to set the terminal type.
