electron-serialport-poc
This test assumes you have a prolific USB to RS-232 Serial Adapter.
Performing Loopback Test
Dependencies
- First you must install the prolific driver for your Operating System.
- After installing and restarting your system, you must next identify the port for testing. For example, on Mac you can run
ls /dev | grep tty.usbwhich should returntty.usbserial, if your driver was installed correctly. - Next, install
@serialport/replby runningnpm install -g @serialport/repl - The TXD(3) pin must be connected to the RXD(2) pin. - DE-9 Male diagram
Performing Test
- Now let's perform the test in the serialport repl!
serialport-repl {path-to-port} # serialport-repl /dev/tty.usbserial on a Mac
# This will pre-load a `port` variable with a connection to the serial adapter.
> port.open() # Allow the port to accept I/O
> port.write("Hello World!")
> const output = port.read()
<Buffer 48 65 6c 6c 6f 20 77 6f 72 6c 64 21> # If connection between pins was successfully made
> output.toString(); # should be "Hello World!"
