## = number of events running.
NOTE: X1! = Version number listed to 2 decimal places
X3% = Event number range: 0 to 99
X3^ = Event buffer 0 = receive, 1 = unied, 2 = data, 3 = NVRAM
X3& = Event buffer offset 0 to MaxBufferSize
X3* = Event data size b = bit, B = byte (8 bits), S = short (16 bits), L = long (32 bits) This parameter is case sensitive.
X3(= Event data to write
X4$ = Number of bytes to read 1 to 24 max
X5$ = ASCII digit(s) representing the numeric value of the data element read from the event buffer (leading zeros are suppressed)
