Expect script does not complete
I am new to Expect and need an expect script to expect data from a telnet session and respond with options as written in the script. There is no human input required. Problem is it gets to a point in the script and will just end. I have tried adjusting 'set timeout' and still does not help.
The code looks like this:
set timeout 30
match_max 2000

expect -timeout 3 -exact "Add Information"
expect -timeout 3 "THISWILLNOTBEFOUND"
-send -s <the data here is going through a series of input fields>
-send -s <the data here is going through a series of input fields>
-send -s <the data here is going through a series of input fields>
-send -s <the data here is going through a series of input fields>
-send -s <the data here is going through a series of input fields>
-send -s <the data here is going through a series of input fields>
-send -s <the data here is going through a series of input fields>

All of the data is input properly and the 'Add Information' screen is displayed again with a message that the data input had been successful.
I would like to <ENTER>, go to the next screen and continue with additional work. However, the script ends.

usb_control_msg

USB_CONTROL_MSG(9)						   USB Core APIs						USB_CONTROL_MSG(9)

NAME

       usb_control_msg - Builds a control urb, sends it off and waits for completion

SYNOPSIS

       int usb_control_msg(struct usb_device * dev, unsigned int pipe, __u8 request, __u8 requesttype, __u16 value, __u16 index, void * data,
			   __u16 size, int timeout);

ARGUMENTS

       dev
	   pointer to the usb device to send the message to

       pipe
	   endpoint "pipe" to send the message to

       request
	   USB message request value

       requesttype
	   USB message request type value

       value
	   USB message value

       index
	   USB message index value

       data
	   pointer to the data to send

       size
	   length in bytes of the data to send

       timeout
	   time in msecs to wait for the message to complete before timing out (if 0 the wait is forever)

CONTEXT

       !in_interrupt ()

DESCRIPTION

       This function sends a simple control message to a specified endpoint and waits for the message to complete, or timeout.

       If successful, it returns the number of bytes transferred, otherwise a negative error number.

       Don't use this function from within an interrupt context, like a bottom half handler. If you need an asynchronous message, or need to send
       a message from within interrupt context, use usb_submit_urb. If a thread in your driver uses this call, make sure your disconnect method
       can wait for it to complete. Since you don't have a handle on the URB used, you can't cancel the request.
