Probably better:

   grotty: Input data not suitable for a TTY device.

This data is already available: The device's DESC file contains the
postprocessor to be used.  A compiled-in table makes it impossible to
add new devices without recompiling (at least currently since
different output encodings are treated as different devices).

So the process is as follows:

  . Get the device name from the `x T device' line.

  . Read the device's DESC file and get the value of the `postpro'
    keyword.

  . Check whether the current postprocessor is identical to the
    `postpro' value, abort otherwise.
