Byte Offset
Description
251 to 252
Number of characters (0 to 200) in Port 2 receive block (255 to 454). If the receive
data in the module is larger than 200 bytes, multiple blocks will be transferred. Any
block with a value of -1 in this field represents the first or continuation block and the
block contains 200 bytes of data. The last block of data will contain a positive
number in this field that represents the number of characters in the last block.
253 to 254
Number of characters transmitted (0 to 200) from last block write Port 2
