Jan 26, 2009 Serial Ports. Discussion in 'Proxmox VE. How do I enable Serial port so that I can use. I just uploaded a new version which supports serial device pass through.

I installed qemu-server_1. Free Reports For School. 0-8_all.deb package but is not working as I expected. In the virtual machine (Windows XP) appeared a new COM port (COM2) but the modem installed on Windows is not communicating with the real device. On the host machine I tried to see if /dev/ttyS0 is in use. The command 'lsof -l grep /dev/ttyS0' give me the following result kvm 3960 0 18u CHR 4,64 7785 /dev/ttyS0 kvm 3983 0 17u CHR 4,64 7785 /dev/ttyS0 Earlier I made some tests with 'cu' to communicate with the modem and the only way it worked was to put 'uucp:uucp' as owner of '/dev/ttyS0', otherwise it returned the error 'line in use'. So I think that now is maybe a rights problem, but I have no ideas how to solve the problem.
