I have a new TrippLite SmartPro UPS 2200 I am attempting to manage via a box running SLES9. I connected the supplied DB-9 serial cable to the server, installed the PowerAlert monitoring utility and launched the console. The console says it can't find any UPSes. The command prompt from which I launched the console reports: ERR: VarRecord.update: PDU error 5 I believe this is a generic snmp error, likely indicating there is no communication between the UPS and the server. TrippLite tech support did not want to talk to me once I told them the box was running SLES; they claim they only support Linux. The tech did eventually volunteer that most problems are because the serial port needs to be set to 2400 baud. (He also told me his docs had no info for parity, data bits or stop bits, so who knows...). Being a newb to serial ports under Linux (but knowing a bit about serial ports in principle having done beta testing for Hayes years ago), I'd like to know the following if some kind soul could help: 1. Do I need to load a kernel module to get the serial port fully functional? setserial correctly reports the uart type already. 2. How do I set the parity, data and stop bit settings for the port (I'll start with N-8-1, preferably). 3. I think the port is already at 2400 baud, but I'd like to run something at boot time that definitely initializes the serial port. Setserial? Thanks!
