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 5200 uses 2 TCP ports for communication between the NPort 5200 and host computer's
Real COM driver. NPort 5200 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 5200 from 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 5200 Administration Suite. Refer to the IPSerial directory for
more detail about the function definitions.
