We are not "on call". If someone doesn't answer your question immediately, and you have no further information to provide, wait! I didn't get here just because you bumped it.
"spawn id exp4 not open" is the message expect gives when the thing you're communicating with, telnet in this case, dies while you're trying to use it. Try telneting to that IP / port manually and see what it does.
Your shell script can probably be made far more efficient -- you don't need the help of head, tail, and cut to read and tokenize lines from a file one by one, there's a command just for that.
Hello hello, did a quick search and didn't turn up anything helpful. I've got a book I'm sure has the answers, but I don't think I'll have time to finish it before this all has to work, so here goes~ if this isn't a good place to post and someone could direct me to another forum I'd appreciate...

__________________________________________________________________________________________________________________________________________________NAME
udp - Send and receive UDP datagrams.
_________________________________________________________________DESCRIPTION
The udp command allows to send and receive datagrams using the User Datagram Protocol (UDP) (RFC 768).
UDP COMMAND
udp open [port]
The udp open command opens a UDP datagram socket and returns an udp handle. The socket is bound to given port number or name. An
unused port number is used if the port argument is missing.
udp connect host port
The udp connect command opens a UDP datagram socket and connects it to a port on a remote host. A connected UDP socket only allows
to send messages to a single destination. This usually allows to shorten the code since there is no need to specify the destination
address for each udp send command on a connected UDP socket. The command returns a udp handle.
udp send handle [host port] message
The udp send command sends a datagram containing message to the destination specified by host and port. The host and port arguments
may not be used if the UDP handle is already connected to a transport endpoint. If the UDP handle is not connected, you must use
these optional arguments to specify the destination of the datagram.
udp receive handle
The udp receive command receives a datagram from the UDP socket associated with handle. This command blocks until a datagram is
ready to be received. In most cases, it might be a good idea to check for pending datagrams using the udp bind command.
udp close handle
The udp close command closes the UDP socket associated with handle.
udp bind handle readable [script]
udp bind handle writable [script]
The udp bind command allows to bind scripts to a UDP handle. A script is evaluated once the UDP handle becomes either readable or
writable, depending on the third argument of the udp bind command. The script currently bound to a UDP handle can be retrieved by
calling the udp bind command without a script argument. Bindings are removed by binding an empty string.
udp info [handle]
The udp info command without the handle argument returns a list of all existing UDP handles. Information about the state of a UDP
handle can be obtained by supplying a valid UDP handle. The result is a list containing the source IP address, the source port, the
destination IP address and the destination port.
