The PC serial port should be connected to the USB serial adapter that is connected to the 825 with a crossover cable such as Cardinal 8545-B099-0A. The default baud rate is likely 9600. Settings can be changed with the stty command such as: {{{ card825gen2:~$ stty -F /dev/ttyUSB0 115200 raw -echo card825gen2:~$ echo "hello" > /dev/ttyUSB0 }}} CommView will show: {{{ hello[LF] }}} To test receiving data type: {{{ cat /dev/ttyUSB0 }}} Type in CommView "1234567890" {{{ 1234567890 }}} 4/5/2023 Found prolific driver was not included. Updated build config to include Prolific. Now supports FTDI and Prolific chip based USB to serial adapters. Device files /dev/ttyUSB* will be created automatically when USB to serial devices are connected, and removed when USB to serial devices are disconnected.
