Econet_NetworkState
(SWI &4001A)
| Entry | |
|---|---|
| R0 | Station number |
| R1 | Net number |
| Exit | |
|---|---|
| R0 | Preserved |
| R1 | Preserved |
| R2 | Transport state: |
| 0 = fully functional | |
| 1 = no clock |
Use
The purpose of this call is to return the state of the underlying transport to a given station.
Notes
The state returned is transport type dependent, but you may always assume that a value of zero means that the transport is fully functional.
You should only use the returned value as a hint to the exact state; in other words, it is suitable for display but not for decision making. Using this call is no substitute for proper error handling; to determine if a particular transmit will fail, you must do the transmit and be prepared for it to fail.
This SWI is re-entrant.
