hello device driver gurus, I'm migrating an old mini-computer machine control application to sun sparcstations. This Data General operating system has what is termed a "real time" os. Fast response to interupts is the driving function of this software. Basic functions of the application actually run in micros in the "machine" sending interrupts to my software. Several rs-232 ports are genned into the system and subsequently provide a steady stream of interrupts to tell us what to do next. The code in effect waits for an interrupt and the acts and then waits again (multi-user, multitasking). My question is the terminology/hints for handling these devices. Do i need a new device driver, or hook to the one on the sun? We will be using the sun rs-232 ports. Send mail or post. I'll be looking for hints.
