cannot console in or telnet to Router

[joel-metz]

Router console connection will not open and connect. Cannot telnet to the Router as well. Any suggestions? This is on a frame relay hub and spoke router that is in production. Thanks!

Try changing the speed in Hyperterminal (or whatever ap your using). Maybe someone changed the speed of the port.

Speed in the terminal emulation software could be the issue and flow control should be set to none. Also, it could be caused be memory problems. If memory gets highly utilized or fragemented telnet and console sessions won't open and the only fix is a reboot.
