[S390] sclp_vt220: speed up console output for interactive work
Currently an output buffer can wait up to HZ/2 until the buffer is flushed. The wait time is noticeable in interactive tools like mc. Change the value to HZ/20, which seems enough for interactive work. Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
