11. 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 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.
The NPort serial device server uses 2 TCP ports for communication between the NPort and host computer’s
Real COM driver. The 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 the NPort 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 Administration Suite. Refer to the IPSerial directory for more detail about
the function definitions.
