Hi, have tried loop back. comport ok. and verify that the protocol and serial data send out from PC is correctTry loopback first. Connect TD to RD, CTS to RTS, DTR to DSR. You may only need the first one. Check for echo or a double echo so at least you know your port is working. Hyperterminal was removed from win 7, but if you place the dll and the application in the same directory it should work under win 7.
once connected to the signal gen, the signal generator output a error "RS232 Framing error" Chapter5 236 (https://www.home.agilent.com/upload/c...DE_ENGLISH.pdf)
May i know what is this? anybody encounter this?
is it because of 'floating point'
