hi team, My customer has used the Vc5090 for almost one year. Recently, they encoutered the "time out " case. They selected the wavelink telnet to connect the dataserver. We have done test for this case and write here, hope anybody can give me some suggestioes. 1. When "time out" occured, we can't ping to the terminal. 2.In the same time, the terminal continue to send the reconnect packet to server. After the several time trys, the termianl displayed "timeout". We need to relogon onto the system on terminal. i confused even the network connection is loss during the roaming, who send the reconnect packet to server. thanks zhiguo
