I'm trying to open a serial port with pyserial on a Compaq Deskpro EN
machine. Operating system is FreeBSD 10.10 RELEASE, i386.
root@merleg:~ # kldload scc
root@merleg:~ # python2.7 -m serial.tools.list_ports
no ports found
root@merleg:~ # whoami
root
Here are all the devices:
root@merleg:~ # ls /dev
acpi ctty klog stdin ttyva
ad0 cuau0 kmem stdout ttyvb
ad0p1 cuau0.init log sysmouse ttyvc
ad0p2 cuau0.lock lpt0 ttyu0 ttyvd
ad0p3 cuau1 lpt0.ctl ttyu0.init ttyve
ada0 cuau1.init mdctl ttyu0.lock ttyvf
ada0p1 cuau1.lock mem ttyu1 ufssuspend
ada0p2 devctl midistat ttyu1.init ugen0.1
ada0p3 devstat mixer0 ttyu1.lock ugen0.2
agpgart fd nfslock ttyv0 uhid0
apm fd0 null ttyv1 ukbd0
apmctl fido pass0 ttyv2 urandom
atkbd0 geom.ctl pass1 ttyv3 usb
audit gptid pci ttyv4 usbctl
bpf io ppi0 ttyv5 xpt0
bpf0 kbd0 pts ttyv6 zero
cd0 kbd1 random ttyv7
console kbd2 sndstat ttyv8
consolectl kbdmux0 stderr ttyv9
And here is what I see in dmesg:
root@merleg:~ # dmesg | grep uart
uart0: <16550 or compatible> port 0x3f8-0x3ff irq 4 flags 0x10 on acpi0
uart1: <16550 or compatible> port 0x2f8-0x2ff irq 3 on acpi0
Obviously the question is: how do I open the COM port from pyserial on
this machine?
