ENQ    
询问

询问

1. /enkw/ or /enk/ ENQuire. The {mnemonic} for
{ASCII} character 5.

2. An on-line convention for querying someone's
availability. After opening a {chat} connection to someone
apparently in heavy hack mode, one might type "SYN SYN ENQ?"
(the SYNs representing notional synchronisation bytes), and
expect a return of {ACK} or {NAK} depending on whether or not
the person felt interruptible.

Compare {ping}, {finger}.

[{Jargon File}]
