Add : VxComm Utility, add the "Check Duplicate" and "Check Server" options. Check Duplicate : This option will check the IP address if duplicated with the exist servers. Check Server : This option will connect to the IP address and get the server's name. Fix : Changes the number of session (array) from 3 to 9, this supports up to 8 ports (7188E8).
