VMware Workstation can connect the OS running in a VM to a physical serial port (as well as many other devices, but we're speaking serial ports here). You can assign, in the "edit virtual machine settings" screen a virtual serial port to be attached to a real physical serial port. Further, once the VM is booted, you can click the VM menu, then "removable devices" and then select the serial port and choose "connect" or "disconnect". I suspect the person who asked about this wanted to know if the phyisical serial port was or was not in a "connected" state in the windows VM. I would assume, as did he, that if it IS connected to the VM, that the LInux system would either not be able to use it at all, or that it wouldn't work right if it did. > > Strange, but what than I select /dev/ttyS* when configuring the VM machine? > Just for compatibility? > > And tehre is absolutely no problem with permissions - I guarantee. > > [sergie@local ~]$ ls -l /dev/ttyS0 > crw-rw-rw- 1 root uucp 4, 64 Сен 10 00:46 /dev/ttyS0 > > Here even "nobody" or any other user on the system has access. > Why kermit says nothing when you looose the UPS power?
