Kim Woelders	4d1d6978e4	Don't clear readable flag on poll When the slave becomes readable we set the pollin flag, and cleared it in ttynvt_poll(). So if ttynvt_poll() is called twice, the readable flag was lost. Now we clear it in ttynvt_read() if there actually are no more data to be read.	2019-01-16 11:17:18 +01:00
