the VTR will accept commands from the personal
computer. in the case of EVT, EAT, EIT, SPT, SCS,
SCP, OSR, OSF or CCL, the VTR will return a

CCL
This is the counter calibration command. It resets the
counter after the tape has been rewound to the
beginning. It can be executed if the VTR is in the
STOP, PLAY, REW, FF, PLAY PAUSE, REVERSE
PLAY, SLOW or SLOW PAUSE mode. It can be
canceled by the OSP or OEJ command. The counter
calibration operation will be canceled if the operation
mode changes as a result of a key input from the
VTR proper or the remote controller. If the VTR
receives a command other than the OSP, OEJ, QCD,
QOP, QOS, RCK, QRV or QID command while the
counter is being calibrated, the VTR will return a
command error.

hence
the
