I have done the script before myself and well familiar with the error
message you are getting. It took me about a week to figure out. Error
message you are getting is caused by router prompt. Try to push prompt
command to match the router prompt prior to calling the tftp copy. Let me
know what your outcome is.

Brennan,
If you have SNMP RW access to the router, use SNMP to upload the IOS. It's
much more painless process than any telnet/expect script. A command like
below will do the job.
This command will erase the existing image from flash.
snmpset 172.16.99.22 private .1.3.6.1.4.1.9.2.10.6.0 i 1
Where: i 1 defines the file index in the flash.
This command will copy the new image to your flash.
snmpset 172.16.99.22 private .1.3.6.1.4.1.9.2.10.12.171.68.191.135 s
c2600-i-mz.122-2.XA.bin
Where: 171.68.191.135 is your TFTP server address and
c2600-i-mz.122-2.XA.bin is image name.
I have tested this in lab and have found better results than writing a
telnet or expect script. However if you write your telnet perl script and
don't mind sharing, I would like to use it on some of my antique devices
those do not support Cisco FLASH MIB.
Hope this helps.
