D2+1 (Transmit Digits (Bytes))
The transmit data byte count is stored in the data register after that set with D2 (D2+1). BCC data is also included in the transmit
data byte count.
The data register next to the device designated for transmit status stores the byte count of data transmitted by the TXD
instruction. When BCC is included in the transmit data, the byte count of the BCC is also included in the transmit data byte count.
Example: Data register D100 is designated as a device for transmit status.
