- I have a Topaz/Square D CUB Powermaker UPS, on a 486 based system running
- SVR4. The unit is equipped with a DB9 connecter and some simple relays that
- show loss of AC power and low battery. The manual says that user supplied
- software and cable are required to make use of this feature.
-
- Is there any simple software kicking around that allows one to use an RS232
- port to monitor the UPS like this. It seems that some of the standard RS232
- control lines could be used for this purpose.
-
- The pin-out of the DB9 connector and the Truth Table is as follows.

- 5 4 2 2 1

- BATTERY LOW XXXX CLOSE XXXX OPEN

- Any help with this would be greatly appreciated.
