CAICCI/PC

On Windows, you can use the CAICCI/PC Properties TCP/IP tab to set two additional timeout values.

Ready to Receive: Specifies how long CAICCI/PC waits for subsequent TCP/IP packets after receiving the initial reply packet. Unless the network is extremely congested these usually arrive very quickly, and this timeout is seldom exceeded. The default value is '-1', which causes CAICCI/PC to wait indefinitely. This rarely causes problems, but a value of 60 seconds is reasonable to ensure that no reply can cause the application thread to hang.
Ready to Send: Specifies how long CAICCI/PC waits to send data on a socket. Since sockets are full duplex, there is almost never any wait at all. The default setting of 60 seconds is generally acceptable.

These timeouts are not needed when using the Type 4 JDBC driver.
