From Jargon File (4.3.1, 29 Jun 2001) [jargon]:

  ENQ /enkw/ or /enk/ [from the ASCII mnemonic ENQuire for 0000101] An
     on-line convention for querying someone's availability. After opening a
     {talk mode} connection to someone apparently in heavy hack mode, one
     might type `SYN SYN ENQ?' (the SYNs representing notional
     synchronization bytes), and expect a return of {ACK} or {NAK} depending
     on whether or not the person felt interruptible. Compare {ping},


     {finger}, and the usage of `FOO?' listed under {talk mode}.
