Hi,

The server's driver framework has alternative implementations for vbar, 
hbar, cursor, bignum, icon and heartbeat functions, that will be used if 
the driver does not implement the function. For the heartbeat this 
alternative function is implemented by calling the icon function for the 
ICON_HEART_OPEN and ICON_HEART_CLOSED icons you mentioned. The icon 
function alternative will place the "#" "-" and "+" characters you also 
mentioned. All this is in server/driver.c

Maybe you already knew this, I hope this can be of help.

The heartbeat can also be disabled on global, per client or per screen 
level. Then only a ICON_BLOCK_FILLED is drawn.
