Details:

This patch addresses bug #48767.  Unlike the POSIX network programming
functionality, the Win32 networking programming functionality did not include
a working version of the "ser_drain(...)" function.  This function is
responsible for draining any stray characters from the programming device
before attempting to synchronize with the programmer for the actual
programming task.  The "ser_drain(...)" function did get used when attempting
network programming, but it always failed because it attempted to use the
Win32 "ReadFile(...)" API to read data from a WinSock socket, which is
illegal.  Hence, the actual programming would fail if there were any stray
characters queued, causing a synchronization problem between the host and the
programmer.
