OFC Signal is Solid on Digi One and PortServer


Port is configured for autotelnet and does not get a login prompt.

When port signal information is displayed, the OFC signal is lit solid (seen on LED front panel on PortServer and PortServer II products; use DPA Remote or [display ports] for Digi One and PortServer TS products).


  • Try pressing [Ctrl q] from a terminal/device connected to the port.
  • Use the who command to kill the port process then try to configure the port for software flow control:
kill tty=[port-number]
set flow range=[port-number] ixon=on ixoff=on cts=off rts=off
