serial port. The DSX16 and DSX32 models have only one external DB9M serial port (labeled
TERMINAL).
Both ports support a VT100 terminal or equivalent (PC running VT100 emulation software, for
example, HyperTerminal, or Linux Minicom). Local port access must be enabled and set to the
same speed as the managed device for it to work. Local port access can be enabled or disabled
from the GUI and the CLI using the lpa command through SSH or Telnet, if it is enabled. The
telnet server on the Dominion SX unit is disabled by default.
Models with two terminal ports support an external modem on only the port with the RI signal.
On models with only one serial port, a modem is built in. The externally accessible serial port
does not include the RI signal so it supports only devices such as a VT100 terminal or equivalent.
The following table identifies the first DB9M serial port pinouts.
