The IP Serial Library is a collection of Windows functions for

NPort 5000 device servers. Serial command sets and common

subroutines are provided. The purpose of the library is to help

reduce complexity and increase efficiency when programming

for serial communication over TCP/IP. For example, the IP Serial

Library can be used to add new functionality to your Telnet

sessions, since Telnet can only transfer data and can not monitor or

configure serial line parameters.

IP Serial Library eases

programming for socket-based

serial communication

For programmers who are familiar with serial communication, the

IP Serial Library provides well-designed function calls that have the

same style as MOXA’s PComm Library.

The IP Serial Library is amazingly simple and easy to understand.

By including the library in your VB, C, or Delphi programming

environment, you will be able to develop TCP/IP applications that

have control of serial communication parameters.

When Real COM mode is used, NPort serial device servers use

two TCP ports for communication between an attached device

and a host computer’s Real COM driver. The two ports, a data port

and a command port, provide pure data transfer without requiring

encoding and decoding. With the IP Serial Library, only one port is

used to communicate with a user's application, and no encoding or

decoding is required.
