There is more. Reading form the sio(4) man page the error is reported as follows: sio%d: tty-level buffer overflow. Problem in the application. Input has arrived faster than the given module could process it and some has been lost. Could it be a problem with the tip application, to be eventually reported as a bug? Regards, Marco
