VMware Telnet Session

To establish a VMware telnet session for remote serial port communication, a virtual machine and a proxy participate in a message exchange that follows the model of a standard telnet protocol sequence. The proxy handles messages from the virtual machine and sends the appropriate responses. Before the proxy can forward content, the virtual machine and the proxy participate in the following progression.

1. The virtual machine and the proxy negotiate the use of the VMware telnet extension option.

   Both sides of the connection must agree to use the option before continuing with any additional extension message exchange.

2. The virtual machine and the proxy identify the VMware telnet suboption commands that they support.

   The proxy must support the KNOWN-SUBOPTIONS-2 and UNKNOWN-SUBOPTION-RCVD-2 commands. During a session, the proxy can send the UNKNOWN-SUBOPTION-RCVD-2 command as a valid response to virtual machine messages.

3. The proxy agrees to act as a VMware telnet extension proxy for remote serial port communication.
