int rn_enable_wdt(int handle, int wdttype);
int rn_hitwd(int handle, char *count);
Enables the hardware and/or software watchdog timers on a peripheral card. The software on the periph-
eral card will keep the hardware watchdog timer updated, but will hard reset if the time expires. The
hardware watchdog cannot be disabled except by a hard reset on the peripheral card. The software watch-
dog timer must be updated by software on the master. The peripheral card will soft reset if the timeout set
by rn_sw_wdt() expires.

handle is an address index to device information. Use rn_device() or rn_find() to establish the
handle.
wdttype
The status byte from the previous command. -1 means that device information indicates the peripheral
card is not connected to the master.
Hits software watchdog. Set the timeout period and enable the software watchdog prior to using this
function.

count is a pointer to return the present count of the software watchdog timer. The equivalent time left in
seconds can be determined from count × 0.025 seconds.
The status byte from the previous command. -1 means that device information indicates the peripheral
card is not connected to the master.
