Serial Interrupt

[kduck63]

i was considering using a 18F2553 which does have the baudcin bits. If i set them appropriately, is it a similar hook up as shown in the pbp manual with the current limiting resistors?

While I don't recommend the "no MAX232 approach" to anyone - certainly not for a production unit, it works. If it works on a SERIN pin, it will work on a HSERIN pin as well.

There is only one small drawback to using the hardware in the way I mention - you can't set it for open-collector (open drain) operation without an external transistor or gate. That mode can be very useful in small networks.
