Note:
Local ports: Each 2 byte data represent current local port setting of the corresponding serial port. Local ports data
length of PS100 should be 2 bytes, while 4 bytes and 8 bytes for PS200 and PS400 respectively. Configured
local TCP (or UDP) port numbers for each serial port are filled with network-order bytes, (i.e. higher bytes first). If
the host mode of a serial port is set to client mode, the local port number is regarded as 0.
Example of the PS100:
If port number = 6001 (1771h), Local ports data = 17h, 71h
If host mode is TCP client, Local port data = 0h, 0h
Example of the PS400:
Port1 = 6001 (1771h), Port2 = 6002 (1772h), Port3 = TCP client, Port4 = 6003(1773h)
Local ports data = 17h, 71h, 17h, 72h, 00h, 00h, 17h, 73h
