Notes on  ENQ 

[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.
