NPort IA5150A/IA5250A Series 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 IA5150A/IA5250A serial device servers use 2 TCP ports for communication between the NPort
IA5150A/IA5250A and host computer’s Real COM driver. The NPort IA5150A/IA5250A 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 RFC2217), IP Serial Library uses a command port to communicate
with the NPort IA5150A/IA5250A in 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 IA5150A/IA5250A Administration Suite. Refer to the IP Serial directory for
more detail about the function definitions.
