After writing characters to a real port, the driver should timeout the transmission and after the total time expired, TEMT can be set. + +Some applications i.e. with a simplex modem do: RTS_on, WRITE_data, repeat IOCTL(GET_LSR_INFO), RTS_off, READ_data. +At the moment this fails because very early in the transmission, GET_LSR_INFO returns true and the modem transmitter is switched off. + +I looked in the source (git) and found that 'char_transmit_time' is present. My skills fail to implement it myself. +I build and ran the latest git version and found it to fail as decribed above. I hope someone can solve it.
