No. 560	EZVSP	2010-06-22

Hello I have used ezvsp 2.3b software for creating a virtual serial port with EZL 70 device working in client mode (COD2) COM8 port has been succesfully created When I open an RS232 application program I get the indication Port OPEN 9600 8 n1 but when i try to send a protocol command to the serial device I get no response However, the communication in the TCP server (the server in which EZL 70 is connected) is correct and I can see the serial messages from the RS232 device coming on the TCP server messages from TCP server to the serial device are properly transfered and the RS232 device responds correctly The problem is that I can not send transmitting message from the normal RS232 control program to the serial device through the serial port It seems that the command is sent to unit ( is shown on the TCP server) but the RS232 device does not respond I would highly appreciate any help
