PORT~MASTER‚Ñ¢ allows you to reset the Macintosh parameter ram (PRAM) settings which specify the default configuration of the Macintosh serial ports.
I had noticed that there are no programs (that I know of) which utilize the default settings. That is all of the programs which deal with the serial ports
(communications packages, etc.) all have their own code in them to modify the serial ports.
This I feel is a lot of redundant overhead which the Mac should be able to handle within the operating system. Thus was born 'Port~Master‚Ñ¢' which is a cdev which allows the modem (and printer port) configuration to be set from the Macintosh control panel!
This would allow developers to make their code simpler in that it removes the onus of setting ports. This in turn either should make communications programs smaller (important in Multifinder universe) or more featured. In either case the Mac benefits.
I'm surprised that Apple hasn't provided something similar as part of the standard system.
If you are writing code that will use the default settings, you need only open the serial drivers, and read/write your data. You do not need to worry about the settings of the ports.
The "Port~Master‚Ñ¢" cdev is freeware. However, if you would like to include this as part of some commercial package, please contact us.
