Hello all I'd like to get some instruments data by serial port (COM1 - win32) I make a loopback serial adapter for a testing with the code: system('mode COM1 9600,N,8,1') ser <- file("COM1", open='r+') isOpen(ser) write('12345', ser) scan(ser, what=as.character(1), n=1) So I get the data that I wrote in the port... But I don't have a more fine control about the serial configuration with this approach like timeout, handshake etc... Is there a specific package (library?) for hardware communications? ( For serial port specifically ) Thanks Cleber _______________________________________________________ Experimente j? e veja as novidades.
