Hello. You can drop all the data, which had received from RS232 port before the connection is established, by using an option. The option'ss name is . If you activate this option, ezTCP won'st send the serial data to the remote host. This option is only for the TCP client mode and available only under condition that the parameter is set to zero. If the option is not available, please check your firmware version. 1.2C or subsequent versions are available.

EZL70 works as a TCP client CODs Serial line settings are: 9600,8,N,1,None.
