Overview
What is the IP Serial Library?
The IP Serial Library is a Windows library with frequently used serial command sets and
subroutines. It is designed to reduce the complexity and improve the efficiency of serial
communication over TCP/IP. For example, Telnet can transfer data but cannot monitor or
configure the serial line’s parameters.
Why use the IP Serial Library?
For programmers who are familiar with serial communication, the IP Serial Library provides well-
designed function calls in the style of MOXA’s PComm Library. It is simple and easy for
programmers to understand. You can include the library in your Visual Basic, C, or Delphi
programming environment and easily develop your own TCP/IP application with the ability to
control serial communication parameters.
With the Real COM driver, two TCP ports are required for communication between the NPort and
the host computer. The IP Serial Library requires one command port to communicate with the
NPort. Serial communication can be controlled with just one TCP port (e.g., RFC 2217). The IP
Serial Library not only runs with excellent efficiency but also runs without any decode or encode
problems.
How do I install the IP Serial Library?
The IP Serial Library comes with the NPort Administration Suite. Please refer to the IP Serial
directory for details about the available functions.
