Background information:
Socket programming is this easy ...
One of the easiest ways to create network connections is provided by Microsoft Visual Basic, version 5.0 and higher. This lets you send data over the network even without any special knowledge of network operations. Our sample program shows you how just 30 lines of source text and our Com-Servers are all you need to send serial data over the LAN/WAN.
Our download area also contains sample programs in C, C++ and Java, as well as an example for the UNIX platform.
If you don’t already have them, here are the most important development kits for the various platforms:
| Software platform |
Development kit |
Source |
| WINDOWS 3.11/95/98 and NT |
WINSOCK.DLL is a standard component of Windows and supported by any SDK |
For older Windows 3.11 installations inclusive documentation available free of charge from Microsoft |
| |
TCP/IP tool kit for Visual Basic |
Catalyst Software, California |
| UNIX |
A Berkeley socket API is included in every development system. |
|
| DOS, very old WINDOWS versions, OS/2 |
"LAN WorkPlace for DOS Toolkit SDK" |

Alternative approach:
The Langner Universal Communications API (= LUCA) provides for integration of all current protocols and media into your own application using a single software interface (API) No special knowledge of the protocol or transmission medium is required. Subsequent changes to the application with respect to communication ports can be made quickly and easily.
Supported protocols:
TCP, UDP, Telnet, FTP, HTTP, POP3, SMTP, 3964R, Class2 FAX, X.75, ZModem, XModem, ATModem, UUCode, Frame Relay, HDLC, HDLC Framing, SDLC, T.30, VOICE
Supported media:
RS232/422/485 using COMM.DRV, network using winsock.dll/Berkley-Sockets, ISDN using CAPI, etc.
