4.13 Preferred Packet Size
Preferred Packet Size specifies the maximum number of characters in a data packet. If
left at 0, data will be sent in amounts equal to the maximum network packet size

mulates data before sending it, which can help reduce network overhead.

1 Choose Serial Port from the Device Settings menu.
2 Choose Preferred Packet Size from the Serial Port Settings sub-menu.
You are prompted to enter the preferred packet size.
3 Type your preferred packet size and press Enter.
