NPort IA5150/5250 Series User’s Manual IP Serial LIB
7-2
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 IA5150/5250 uses 2 TCP ports for communication between the NPort IA5150/5250 and
host computer’s Real COM driver. NPort IA5150/5250 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 IA5150/5250 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 IA5150/5250 Administration Suite. Refer to the IPSerial
directory for more details about the function definitions.
