How to enlarge the words? [2]

I used the Xstart (Xmanager 2.0) to connect a Linux server, but the words is very small, and my
LCD is 1280*1024 but cannot reduce it. So I want to know how to enlarge the words by some commands, there is no toolbar including these settings. Thanks!

Every xclient has a font option.
For example,
$xterm -fn 8x16
or
$xterm -fn 12x24

Also, you can find fonts whichever you like using xlsfonts command or xfontsel command.

Thanks a lot!
