Hi, I'm having a problem with a serial port and I don't know how to diagnose it. I'm trying to hook up an APC SMART-UPS via a black 940-0024C cable. When I attempt to start the apcsmart driver, I get: judeah# /usr/local/libexec/nut/apcsmart /dev/cuaa0 Network UPS Tools - APC Smart protocol driver 0.60 (0.45.1) Serial port read timed out Unable to detect an APC Smart protocol UPS on port /dev/cuaa0 Check the cabling, port name or model name and try again The cable is good, it's been used on another machine for 6 months. It's fully seated in the serial port. So I check the port with dmesg: judeah# dmesg | grep sio sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0 sio0: type 16550A sio1: configured irq 3 not in bitmap of probed irqs 0 I don't know how to check the port other than issue stty: judeah# stty -f /dev/cuaa0 -a speed 9600 baud; 0 rows; 0 columns; lflags: -icanon -isig -iexten -echo -echoe -echok -echoke -echonl -echoctl -echoprt -altwerase -noflsh -tostop -flusho -pendin -nokerninfo -extproc iflags: -istrip -icrnl -inlcr -igncr -ixon -ixoff -ixany -imaxbel -ignbrk -brkint -inpck -ignpar -parmrk oflags: -opost -onlcr -ocrnl -oxtabs -onocr -onlret cflags: cread cs8 -parenb -parodd hupcl -clocal -cstopb -crtscts -dsrflow -dtrflow -mdmbuf cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = <undef>; eol2 = <undef>; erase = ^?; erase2 = ^H; intr = ^C; kill = ^U; lnext = ^V; min = 1; quit = ^\; reprint = ^R; start = ^Q; status = ^T; stop = ^S; susp = ^Z; time = 0; werase = ^W; A check of irq's with dmesg doesn't reveal any conflicts: judeah# dmesg | grep irq rl0: <Accton MPX 5030/5038 10/100BaseTX> port 0xfc00-0xfcff mem 0xfedffc00-0xfedffcff irq 11 at device 12.0 on pci0 ahc0: <Adaptec 2940A Ultra SCSI adapter> port 0xf800-0xf8ff mem 0xfedfe000-0xfedfefff irq 10 at device 13.0 on pci0 fdc0: <NEC 765 or clone> at port 0x3f0-0x3f5,0x3f7 irq 6 drq 2 on isa0 ata0 at port 0x1f0-0x1f7,0x3f6 irq 14 on isa0 ata1 at port 0x170-0x177,0x376 irq 15 on isa0 atkbd0: <AT Keyboard> flags 0x1 irq 1 on atkbdc0 sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0 sio1: configured irq 3 not in bitmap of probed irqs 0 ppc0: <Parallel port> at port 0x378-0x37f irq 7 on isa0 Does anyone know what's going on here or can tell me how to diagnose this? FYI, I'm running 4.4-STABLE on a Compaq Presario 7170. -- Regards, Doug To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
