Use
The purpose of this call is to read the duration of the first flash colour.
Notes
This call reads the duration of the first flash colour, as set with OS_Byte 9 or VDU 23,9?. This call should not be used to write the value – doing so would only change the value in memory, without affecting the hardware.
The duration of the second flash colour can be read by OS_Byte 194.
