Gilson HPLC Pump RS232 communication

Can be used to communicated with various Gilson pumps via RS232, all connected together using a 508 interface module. This is a slightly simplified version of the code in CO2gui.

serialObject = gilsonpumpobj(comPort) returns the serial object for Gilson pumps given a suitable COM port number (unsigned integer: 1-255). Information can be passed into the serial object through the optional userData argument. Information is stored here as a structure during a communication session with the pump for more efficient communication.

gilsonpumpobjconnect and disconnect(serialObject) work like you'd expect

Various commands are available to communicate with the pump, and due to the way the data is stored if you are retrieving more than one parameter it may be more efficient to collect them at the same time (see the comments in each file).
