It may be cabling between you and the modem - if you don't have the RTS/CTS and DTR/DTE pairs enabling handshake will just disable the port transmit. Try disabling the Handshake - the Modem may specify it but if it ain't there for testing it doesn't matter too much - you can re-enable it when some data is being transferred. Good! So you genuinely have nothing coming out, but you can transmit with Hyperterminal. The apt command needs to know what the latest available packages are.

mkdir /serial cd /serial nano serialwrite.py. Run the following two commands on your Raspberry Pi to start writing the file.
the serial communication does not group transmitted data into packets, or lines of text if you want to send.
To start off, let’s begin writing our serialwrite.py script, this will write data over the serial port. Leave the terminal emulator connected and. You use Python code in another video here. Programming the Raspberry Pi for Serial Writing. Port.Write(writeBuffer, 0, writeBuffer.Length) īut it won't make any difference to data coming out of the serial port.ġ) Are you sure no data is being written? Why? How have you checked?Ģa) Is the port connected to a physical serial port, such as COM1? Are you checking COM1, and have you made sure that you can write to it and talk to the modem with a terminal program (hyperterminal or similar)?Ģb) Have you configured Handshaking? Is so, turn it off (it is off by default)Ģc) Have you enabled RTS and DTR? Try it. Did you wish to send hex text like 0x03 0x8A to Serial Port. Byte writeBuffer = File.ReadAllBytes( " filename.txt")
