From: Max Usachev on 26 Jul 2010 04:50 Hello! I have a problem with UPS FSP EP650 with COM-port and Debian. The device is workable (I have tested it under Windows), but under Linux it doesn't works. My hardware: motherboard: Gigabyte GA-D510UD (Intel NM10, iTE IT8720 chipset) (Intel Atom 510 processor) UPS: FSP EP 650 My software: Debian Squeeze with kernel 2.6.32-5 NUT COM-ports has detected: dmesg | grep tty [ 1.244470] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A [ 1.244596] serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A [ 1.245034] 00:08: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A [ 1.245223] 00:09: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A The same IRQ modes setted in BIOS. but cat /dev/ttyS0 or cat /dev/ttyS1 shows blank screen minicom doesn't work also I use NUT for my ups with following ups.conf: user = root [fsp] driver = apcsmart port = /dev/ttyS0 nas:~# upsdrvctl start Network UPS Tools - UPS driver controller 2.4.3 Network UPS Tools - APC Smart protocol driver 2.03 (2.4.3) APC command table version 2.1 Unable to detect an APC Smart protocol UPS on port /dev/ttyS0 Check the cabling, port name or model name and try again Driver failed to start (exit status=1) Also I tried to write and read something from COM-port using simple program written in Python - no results. A suppose, that it is lowlevel problem with modules or kernel. Can anybody help me?

Try with another driver. > I think, it is general Kernel + COM-port problem Anything in "/var/log/syslog" supporting that thinking? :-? >> Additional data for your review: >> >> *** >> [Nut-upsuser] FSP UPS not listed as supported, but seems to work... at >> least a little... >> http://lists.alioth.debian.org/pipermail/nut-upsuser/2010- April/006023.html >> *** >> > They use UPS with USB port. Yep, and at least seems to be detected. BTW, you can also try asking there, as in NUT list you'll receive updated device support information.
