for example if the program would talk to a serial device on com 4, how would you achieve the same goal via a USB to serial adapter?
Under Linux, serial ports are named as "files" under the /dev directory, usually starting with tty. Real serial ports are usually name ttySx (with x being a number. USB serial ports are usually named ttyUSBx, or sometimes ttyACMx if it identifies as a modem type device. However, there are ways to give a device any name you like based on its model, manufacturer, serial number or other identifying parameters that the device provides. -- Scott
