A digital oscilloscope is ideal for viewing high speed data. Rs232 predates the pc but even with eia 574 and the later tia 232 f the definitions still use dte data terminal equipment such as a pc or equivalent and dce data circuit terminating equipment such as a modem or dumb terminal or any other device as the frame of reference. Use port specify a serial port that will be used in the reproduced communication. Crystal tester schematic circuit diagram.

Sometimes there is no substitute for watching the actual signals. Creating a loop with a paper clip may seem silly but its actually a great troubleshooting tool. Or even two usb to rs485 converters instead. Respond as a device enable this option if you want to send data to a serial port on behalf of a serial device.

The easiest way to connect two pcs is using an rs232 null modem cable. If your computer does not have 2 serial ports you can use a usb to rs485 converter for com2 instead.
