+On Linux's native terminal Linux VT (TTY) it works less well, and not good at all with
+Kernal Mode Settings (KMS) support. See @url{https://github.com/erkin/ponysay/issues/1}
+for more information. @command{ponysay} clears the screen before printing to TTY, this
+is because if your graphics driver supports KMS, the colours will be messed by when the
+ponies position moves on the screen, this is also reason why the output is truncated on
+the height in TTY by default.
+
+Due to extreme limitations in @command{9term} @command{ponysay} will never be able to

+
+Most terminals have support for 256 colours, we do however only use the top 240 colours;
