F-Code ",1" is standby load, which activitates the disc clamp, spins the disc up to speed and, in the case of a CAV disc, displays the first picture frame on the disc in still mode.

The player sends an acknowledgement back to the computer of "S" when the disc is spinning at the correct speed. The short bit of code above repeatedly reads the F-Code response from the player until the spin-up acknowledgement is received. Essentially this is a way of ensuring the computer waits until the disc is ready before sending any more commands to the player.
