Morse rendering

QSL sent as a normal three-letter group (inter-letter gaps included).
As a question
QSL? — Can you acknowledge receipt?
As an answer
QSL — I confirm receipt.
When this is used
On-air 'QSL' = 'roger, copied.' Off-air, a QSL card is the postcard-sized confirmation mailed (or uploaded to Logbook of the World / eQSL) after a contact, used for awards like DXCC.
