1. An infusion pump method comprising: providing a pain controlled analgesic device having a remote controller;operably coupling an infusion pump actuator to a local controller;attempting to send an electrical signal from one of the local controller and the remote controller to the other of the local controller and the remote controller;attempting to receive the sent electrical signal at the other of the local controller and the remote controller; andif the other of the local controller and remote controller does not receive the sent electrical signal, sending an output that is indicative of a frayed cord or an open circuit condition between the remote controller and the local controller. 2. The infusion pump method of claim 1, which includes attempting to send the electrical signal from the local controller to the remote controller. 3. The infusion pump method of claim 1, which includes periodically attempting to send the electrical signal from the local controller or the remote controller. 4. The infusion pump method of claim 1, which includes if the other of the local and the remote controller receives the sent electrical signal, waiting a predetermined amount of time and repeating the attempting and output sending steps. 5. The infusion pump method of claim 1, which includes issuing an alert in response to the output indicative of the frayed cord or the open circuit condition. 6. The infusion pump method of claim 1, which includes indicating (i) audibly, (ii) visually, or (iii) audibly/visually that a cord enclosing an electrical connection between the remote and local controllers is frayed in response to the sent output. 7. The infusion pump method of claim 1, which includes automatically providing a bolus to a patient if a stored amount of time has elapsed since a previous bolus provided to the patient. 8. The infusion pump method of claim 1, which includes sending the output indicative of the frayed cord or the open circuit from the local controller. 9. An infusion pump method comprising: receiving an electrical signal at a local controller that is assumed to be a bolus request signal;in response to the received electrical signal, sending from the local controller to a remote controller a confirm bolus request electrical signal to verify that the received electrical signal is a bolus request signal;waiting for the remote controller to respond to the confirm bolus request electrical signal; andif the remote controller does not respond to the confirm bolus request electrical signal, sending an output that is indicative of a short circuit condition between the remote controller and the local controller. 10. The infusion pump method of claim 9, which includes (i) audibly, (ii) visually, or (iii) audibly/visually indicating that a short circuit condition exists between the remote controller and the local controller in response to receipt of the sent output. 11. The infusion pump method of claim 9, which includes, if the remote controller responds to the confirm bolus request electrical signal, providing a bolus output signal to an infusion pump. 12. The infusion pump of claim 9, which includes communicating the remote controller with the local controller via a protocol selected from the group consisting of: Inter-Integrated Circuit (“I.sup.2C”), Serial Peripheral Interface Bus (“SPI”), Transistor-Transistor Logic Universal Asynchronous Receiver/Transmitter (“TTL UART”); RS 232 Universal Asynchronous Receiver/Transmitter (“RS232 UART”), and fiber optics. 13. The infusion pump method of claim 9, which includes sending the output to a location remote from an infusion pump.
