[Ser2net-devel] gensio 2.8.15, ser2net 4.6.5 released

[Corey M. <co...@mi...>]

This release adds the ability to set the timeout waiting for output to
clear. The default has not changed, but you can set a drain_timeout
option on many gensios that will set the time to wait before dropping
data on the floor and shutting down the connection. This will help in
situations where a remote end crashes or a network partition happens.

This will be the last 2.8.x release with new features. It's going to
maintenance, and I will be starting a 3.0.x series. This will remove the
sergensio code that has been deprecated for a long time.

This release of ser2net improves the failure detection used for
timeouts. It now looks into the transmit queue if possible and sees if
the remote end is accepting data instead of just looking at when it
sends data. In conjunction with the drain_timeout changes in version
2.8.15 of gensio, this means you don't have to rely on the TCP timers,
which can be very long (like 15 minutes in some situations).
