Swapper is a device driver that will save and restore interrupt vectors.
I use this program to disconnect the Laplink3 device driver from the keyboard
service interrupt. To use swapper, put the line DEVICE=Swapper.sys in your
config.sys file. When swapper is loaded a snapshot is made of the interrupt
vectors, then at any time you can cause any of those vectors to be
restored. This will allow you to temporarily deactivate a tsr without
removing it from memory. To set an interrupt vector to its bootup status
type INTSAVE # [#[#[#...]]] where # is the vector number(s) to save. To
reactivate those vectors type INTREST # [#[#[#...]]].
