b. xx:O.Channel[0].Address = starting addressto write

c. xx:O.Channel[0].BlockSize = 0

d. xx:O.Channel[0].Data[0…111] = the data to write

e. xx:O.Channel[0].Length = the number of bytes to write

f. xx:O.Channel[0].Reset = 0

g. xx:O.Channel[0].Timeout = 0

h. xx:O.Channel[0].UIDLow = 0 (or UIDLow)

i. xx:O.Channel[0].UIDHi = 0 (or UIDHi)

Unless a UUID is specified, this command will operate on the first tag in the

field. Specify a UUID in xx:O.Channel[0].UIDLow and

xx:O.Channel[0].UIDHi to perform the command on a specific tag.
