Operating Your V460-XPE Computer with a Telnet Client
Use a crossover Ethernet cable to connect your development workstation directly to the target
computer, or use a straight-through Ethernet cable to connect the computer to a LAN hub or switch.
Next, use a telnet client on your development workstation to connect to the Telnet console utility
of the target computer. After a connection has been established, type the login name and password
as requested to log on to the computer.
After logging in through the Telnet client, a list of commands will be available for operating the
computer. Use HELP to display all of the commands, or type HELP [command name] to display
extended help for the selected command. Some of these commands, such as DATE and TIME, are
very useful for managing the computer’s system time. Other commands, such as DIR and MKDIR,
are good utilities for file management. For example, to inspect the file structure of the root
directory, type DIR.
NOTE: The default user id is “administrator” and the default password is not set; you need to
create a new password for this account to use this telnet client.
NOTE: There is a connection limitation on using Telnet clients. You are only allowed to create
connections with two Telnet clients at the same time.

your system or your data. The data stored in this SRAM is available until the battery runs out of
power. You can use the standard file IO API to read and write data. Sample source code is given
below:
Writing Data to SRAM
// Persisted_SRAM_Write.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <windows.h>
int _tmain(int argc, _TCHAR* argv[])
{
DWORD dwBackSize = 0;
HANDLE hSRAM = NULL;
// open the SRAM device driver
hSRAM = CreateFile(L"\\\\.\\Sram", GENERIC_READ | GENERIC_WRITE,
0, // exclusive access, until the handle is closed
NULL, // no security
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL, // no overlapped I/O
NULL); // null template
if (hSRAM == INVALID_HANDLE_VALUE)
{
printf("Can't open SRAM\n");
return 1;
}
// preparing data for write
char *data = "This is persisted data xxxxxx1234567";
DWORD nLen = strlen(data);
// write data into SRAM
WriteFile( hSRAM, data, nLen, &dwBackSize, NULL);
// close device driver handle
CloseHandle(hSRAM);
printf("** Done! You can now reboot your deivce, and try the Persisted_SRAM_Read program
to verify the data that is still can be read.\n");
return 0;
}
