Scream! 4.5
8.6.2 WRITE-ONCE
Instructs the digitiser to stop writing data to the Flash memory when it
is full, and to switch to DIRECT mode automatically.
For example, in FIFO mode with WRITE-ONCE buffering, the station
will transmit data to you continuously, but also save it in the Flash
memory until it is full. Once full, the instrument will switch to
DIRECT mode and continue transmitting, though no further data will
be saved. This mode thus lets you prioritise the earliest data held by
the instrument.
