For the serial ports on a Linux PC (normally with 16550AF UARTs) you can set-up the CTS/RTS handshake with stty but I did not found a way to modify the number of characters which are sent after CTS -> 0. The default is 16 characters (max.) which is the UART FIFO buffer size. If the terminal on the other end of the line cannot handle 16 characters after CTS -> 0 some data will be lost. Is there a possibility to adjust the FIFO buffer size with stty (or setserial)? Regards, Martin Graefe Germany
