What do you mean by "redirecting the port"? You think vmware toolboxes which start on boot (and got root privileges) might access serial port with no unix participation. 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? It must report that AC is lost. Do you have any more ideas? > As someone else implied, are you sure vmware does not have ttyS0 > redirected??
