Re: using conserver to link vmware virtual machines to Raritan console servers

I've been trying this for Vmware linux and have ran into a similar
issue.  I can't figure out if Vmware supports R/W named pipes.  One
option is to install a multi-port card on the server and each port goes
to a virtual machine.  That is what I'm planning to do.

I tried to create a program that ran on the Linux server that would
interface me using minicom to a pseudo tty.  I told Vmware to use the
slave like normal as its serial port.  Vmware screams that /dev/ttyp0 is
not a serial port.  It is a tty character device so what is
the problem?  If I could get vmware to use /dev/ttyp* as its serial
ports then I would be in good shape.  I know I can use them normally
because when I run my ttyp server for this purpose I can open and read
and write to /dev/ttyp0.
