Synchronous Writes
With Sync writes the client sends the write
and then waits for the response back from
the device before continuing processing. In
most cases there will be no visible
difference between the two. However, if the
device is connected via a modem at
1200baud you would probably see a delay in
processing.
Timeout (Connection)
Used primarily by Ethernet based drivers.
The connection timeout allows the time
required to establish a socket connection to a
remote device to be adjusted. In many cases
the connection time to a device can take
longer than normal communications request
to that same device. The valid range is 1 to
30 seconds.
Timeout (Request)
Used by all drivers to determine how long
the driver will wait for a response from the
target device.
