In a program, data flow diagrams are as important as the function call trees. As we now have some idea of the working how zaptel calls hardware specific functions, let us briefly see how the data is moving across zaptel and hardware drivers.
Responsible functions: ZAP_IRQ_HANDLER, tor2_run
data -> interrupt -> ZAP_IRQ_HANDLER -> tor2_run -> zt_receive / zt_transmit
Details soon...
