"not working" <---We're supposed to know what you mean by this? How about a little more explanation on what isn't working, what errors you're receiving, etc.? Help us help you.

thanks and excuse me for my bad english

so  for example i send "77777"to serial port

but i receive just "7" from serial port

[benyamin200]

i used VSPE software"Virtual serial port emulator" and i make a virtual serial port and i send to hyper terminal

There is a program called dlwedgeutility -> http://www.datalogic.com/tools/download.aspx?iddwnfile=3287&path=%2fupload%2fmarketlit%2fsoftware%2fsu%2fSU-WEU.zip&name=SU-WEU You can at least find out the correct communication settings for your device with this. Works with Windows XP and 7.
