SNAP2411 

SNAPCOM UTILITY 

SNAPCom is a simple TCP/UDP utility program to help familiarize the user with the SNAP and 
its operation. SNAPCom can be executed off the CD or copied onto a PC. There is no need to 
install the program. SNAPCom is not a configuration utility and assumes the SNAP has 
previously been configured using WinSNAP and/or a telnet session. 
The SNAPCom screen is shown below: 

 

TCP Client Operation 

When the SNAP is set to operate as a client in TCP mode, select TCP and Server in the 
SNAPCom window. The PC running SNAPCom will act as the server. The IP address of the PC 
running SNAPCom must be entered into the SNAP as the server using the 

tcp server

 

command. In the Bind Info block of the SNAPCom screen, enter the port number to be used to 
listen to the SNAP in the Port Number window. Click on the Bind button to apply this setting.  
At this point, SNAPCom is listening for open socket requests from the SNAP. The SNAP will 
initiate an open socket request whenever a remote connects with the SNAP. When the first 
remote links with the SNAP, a message indicating the remote has linked along with the IP 
address of the remote will be displayed in the Winsock Information window. The IP address of 
the remote and the Winsock number will be displayed in the Transmit Information block of the
