Appendix C RS-232 Pin Specification
The RS-232 serial port of a TE-100/S14 Switch uses a 9-pin
female connector. The port can be connected to a VT100 type of
terminal, or a PC, or a workstation emulating a VT100 terminal.
For a local connection, the table below shows the pin layout of a
9-pin to 9-pin, or a 9-pin to 25-pin cable connection between the
TE-100/S14 Switch and the management terminal.
