The text is a play on the famous line from Star Trek, 'The engines canna take much more,' spoken by the character Scotty. It replaces 'engines' with 'UARTs' (Universal Asynchronous Receiver-Transmitters) and 'CPS' (Characters Per Second) to create a technical joke that mimics the original context. However, it does not exploit different meanings of a word or similar-sounding words for a humorous effect.
Captain we ' re at 1700 CPS . The UARTs canna take much more
