Until the remote side sends the first byte, we send fill
data since it can take it some time after the mode change
and the file descriptor is open for data to show up.
Previously due to a bug, the warning about short read was
not printed, but now that it's fixed, you get a bunch of
fairly "useless" warning at the beginning of the timeslot.
This fixes that since reported data by _e1_tx_raw is "faked"
until the pipe is active. (Fill data is actually added upstream)
