[time-nuts] Fw: Rb as source for ADEV?

[Bob Stewart]

Hi Orin,

No,
 it's not a matter of just talking to the device.  I can to that.  The 
problem happens when you want more than one program/process to access 
the GPIB bus at the same time; e.g. running two different tests.  For 
that you have to have a server process which manages the interface and 
relays packets to the clients.  Prologix hadn't written one when they 
commented here last summer.

Bob

Porting to Linux/Mac/iOS would be easy enough... maybe I'll do iOS for fun, if Xcode doesn't sulk and stays alive long enough that is; the only thing Xcode does fast for me is crash!
