The NetStatus module controls the display of an hourglass on the screen whenever there is prolonged activity on the Econet.
It claims EconetV, and examines the reason for each call that is made to the vector. It in turn makes an appropriate call to the Hourglass module, so that the appearance of the Hourglass indicates the status of the net. The Hourglass has two 'LEDs', one on top and one on the bottom:
It also displays percentage figures (when it is able to do so meaningfully) which show the percentage of a transfer that has completed.
This table shows how NetStatus converts the reason codes for calls to EconetV (listed in the chapter entitled Software vectors) into the SWI calls that it makes to the Hourglass module:
|Reason code||SWI call|
|NetFS_StartWait||Hourglass_LEDs (both on)|
|Econet_StartTransmission||Hourglass_LEDs (only top one on)|
|Econet_StartReception||Hourglass_LEDs (only bottom one on)|
|NetFS_FinishWait||Hourglass_LEDs (both off)|
|Econet_FinishTransmission||Hourglass_LEDs (both off)|
|Econet_FinishReception||Hourglass_LEDs (both off)|
Versions of RISC OS after 2.0 also change the colour of the hourglass for Broadcast Load and Save calls (as made by the Broadcast Loader). The colours used are:
