Hi, Necessary of aid. I have an address IP and one port, would like to know if it is possible, when using a Socket iSeries, to pass through simultaneous information. Sample: 00019898988826637 -> Send 88787287277726666 -> Send 63565353773737377 -> Receive 65265256552525552 -> Send 32424526263456787 -> Send 52662562552552525 -> Receive 53262625334444244 -> Receive..... all data are transmitted or received simultaneously by the same IP and port, or with delay for the transmission or reception. It is possible, using socket iseries? Thanks --------------------------------- Yahoo! Mail - Com 250MB de espaço. Abra sua conta!
