Serial port pass through too was introduced with ESXi 4.1. The Wiert Corner – irregular stream of stuff Jeroen W. How to access DSA.msc in windows 7. All-In-One Redux - Proxmox & FreeNAS. When pass-through connection is used, the connection pattern will be changed to Y-connection.

I know Xen didn't use to do it, but I was also under the impression that it had been on the 'it's coming' list for so long that it must be there by now. Vmware and virtualbox have had serial and usb pass through for a while. It's only now that I'm looking at how I'm going to build a server for a customer next week, that I've discovered this thread, and I'm disappointed to see that it's still not there, and it sounds like it's still low priority and a long way off, if at all. I've managed to do the fiddle with the iSCSI driver to get windows guests to access a tape on the host and other fiddles with 'network' USB servers to get a windows guess to be able to see a USB security dongle on the host is there some other ('network'?) method of allowing a windows (sbs) or linux (hylfax) guest to be able to see a 9600 baud fax modem on a serial port?

One of the critical questions about the Serial Port native integration is the necessity in the Industrial Automation process or even in little RS-232 controllers apps hosted inside the XenServer. We face this environment with our Parking Control System, where all the communication between the Database Interface and the Hardware is made by a RS-232 and RS-485 network. I'm a senior user of VMware Server, VSphere and lately XenServer solution, and I'm glad to say that you've made a huge step with the friendly interface and the major features for clustering process and also physical resources sharing. That's why I'm so interested in the RS-232 capability, this would solve our needs in 120%. East rochester drivers test routes. Hope to hear news ASAP. No only me but I think everyone that works with Automation processes that heavily depends on serial communication interfaces. Hi Danilo, Feature requests are better suited when posted in the correct forum.

I do understand the requirement of serial pass-through and this can be done on platforms (VMWare) that have full-hardware viurtualization with no pass-through to the physical host. As a work around, it is best to use serial over IP.

I know this has been requested for sometime, but there needs to be a business case for it. The more people who request it, the better likelihood of it getting focused on. If only 1 customer or handful, request it, then it is less likely than a thousand requesting HA (pre-XenServer 5.0). I'm sorry that we have not had this implemented at this time. Regards, James Cannon.

I have spent the last several weeks fighting tooth & nail to get a modem bank to be shared across several VM's and I would like to say that we tried every single product we could find and afford. It boiled down to a seperate physical fax server with multiport modems, that could be shared. We also found that one product would allow class 2 & 2.0 fax but not class 1. MSfax is hard coded to class one, this is a problem if you need it. VMware ESX allows communications to the physical com ports, but we were unable to get them to work reliably, even with supports help. So please get this working soon.

Roger, Citrix isn't hearing these complaints from users because users are choosing to not use your platform due to issues like this. Serial Passthrough is fundamentally basic. This attitude from Citrix of 'if we don't hear thousands of complaints over the same issue, we won't do anything about it' is just not good business.
