Sending RS232 Commands
Via TCP or UDP
TCP and UDP port 57 accept the same serial command set as RS232. It is convenient
for IP control applications and can be tested with a TCP terminal program such as Tera
Term or a UDP terminal program such as Hercules.
Notice the following in the TCP example below using Tera Term:

The IP address is 10.15.0.75

Port 57 is selected

Service is set to "Other" to indicate that TCP is being used without Telnet or SSH
