The purpose of this call is to read the duration of the second flash colour.
Notes
This call reads the duration of the second flash colour, as set with OS_Byte 10 or VDU 23,10?.
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 first flash colour can be read by OS_Byte 195.
