[IGSTK-Developers] number of ports on polaris

[Ziv Yaniv]

Hi Andinet, Luis,

Currently the number of possible ports supported by the 
igstk::PolarisTracker is set to 12. I'm wondering why this specific 
number. From the API specification that I have, the supported number of 
ports is 255:
"The system assigns each tool a port handle. Port handles are two 
characters in hexadecimal format, 0x01 to 0xFF. The two characters 
replace the single character of port numbers and port letters used in 
previous versions of the Polaris API, both in sending commands and 
receiving replies"

If this was an arbitrary decision we should change it to 255 as part of 
the refactoring.

                            thanks
                               Ziv
