You can change the fonts of dtterm by using either of the following methods:
Specifying fonts from the command line
Specifying fonts within a resource file
dtterm -xrm '*fontList: fontset'
where fontset is a font set specification. A font set specification can be specified by a full X Logical Font Description (XLFD) name list, a simple XLFD pattern, or an alias name. Note that a font set specification is determined by the locale that is running.
For example, to use a larger font except for the menu font, type:
dtterm -xrm '*fontList:-dt-interface user-medium-r-normal-l*-*-*-*:'
To use a smaller font except for the menu font, type:
dtterm -xrm '*fontList:-dt-interface user-medium-r-normal-s*-*-*-*:'
Edit the Dtterm resource file in the /usr/dt/app-defaults/language directory.
You can use either the class name (Dtterm) or the application name (dtterm) for a resource file of Dtterm.
Also, setting the LANG environment variable alters the search path of resource files to include the /usr/dt/app-defaults/language directory, where language is the locale name.
After setting the LANG environment variable, the search path for resource files would include the following two folders:
Insert the font set you want to use at the bottom of the file.
For example, to use a monospace font, put this line at the bottom of the file:
dtterm -fn -dt-interface user-medium-r-normal-*-*-*-*
