Abstract
A computer executing a Telnet application manages usage of a system resource by issuing through a transport layer directed to a specific client a DO TIMING MARK command. Responsive to receiving a WILL TIMING MARK or WONT TIMING MARK response from the specific client, the Telnet application calculates a WAIT time; and responsive to receiving no WILL TIMING MARK or WONT TIMING MARK response from the specific client within said WAIT time, the Telnet application causes release of system resource used by the client.
