6.2 Running The Sample Program
Sample programs written in VB and VC++ included in package are provided for ones reference, source
codes are also included. Test program can be found in the product CD or diskette under the directory of
\sample\vb_ap\ and \sample\vc_ap respectively.
There are two test programs, TCPTEST written in Visual Basic and TCPTEST2 written in Visual C++.
6.2.1 TCPTEST in Visual Basic
This sample program is written in Visual Basic 5.0 with Winsock Controls. It shows one how to send and
receive data between host (PC) and GW51C-MAXI Serial Server via Ethernet in two socket ports.
Run Visual Basic and open sample program tcptest. vbp, after the program is started successfully, one
can start testing functions. For more information, please press Help in the program to get detail
explanation.
Note: Please be sure the Microsoft visual studio family software is installed on the computer. Otherwise
