IP Serial LIB 
Overview 
What is IP Serial Library? 
IP Serial Library is a Windows library with frequently used serial command sets and subroutines. 
IP Serial Library is designed to reduce the complexity and poor efficiency of serial communication 
over TCP/IP. For example, Telnet can only transfer data, but it can't monitor or configure the serial 
line's parameters. 
Why Use IP Serial Library? 
For programmers who are familiar with serial communication, IP Serial Library provides 
well-designed function calls that have the same style as Moxa's PComm Library. 
IP Serial Library is amazingly simple and easy to understand. By including it in your VB, C, or 
Delphi programming environment, you can program your own TCP/IP application with the ability 
to control serial communication parameters. 
NPort Serial Device Servers use 2 TCP ports for communication between the NPort and host 
computer's Real COM driver. NPort uses a data port and command port to provide pure data 
transfer without decode and encode. Compared to using only one TCP port to control serial 
communication (such as RFC 2217), IP Serial Library uses a command port to communicate with 
NPort in the user's program. IP Serial Library not only runs with excellent efficiency but also runs 
without any decode or encode problems. 
How to install IP Serial Library 
IP Serial Lib comes with the NPort Administration Suite. Refer to the IPSerial directory for more 
details about the function definitions.
