PROGRAMMING MINI LINK INTERRUPTS
Interrupt Service Routine Location
It is the user's responsibility to install an Interrupt Service Routine at an appropriate
memory location (according to the configured hardware interrupt) which does not interfere
with concurrently operated software or hardware.
In most cases, these interrupt service routines will be simple Transmit/Receive operations
with user conditions determining success or failure of the routines. Table 3-1 lists the
interrupt service vector locations. These are valid for most default system memory maps.

* These addresses are assigned by software only. Because they are not hardwired into
the system, they could be changed by resident or normally terminated routines.
