i know there is a command to adjust ur COM settings(MODE command) but i tried doing the "copy con(keyboard) com1" this lets me copy watever i typed on the keboard to the COM port i specify but i want to create a batch prog similar to WinChat a batch prog that is a chatroom that to users can send and recieve typed words either by using there built in modem(over their phone line) or a direct connection(a connection using a serial cable to connect the two comps.) but how do i create a batch file that can send and recieve commands simultaneously then display them?
