COM Serial Registry Key
OVERVIEW
The COM RS-232 port is located at the bottom of the JNIOR next to the Ethernet
LAN connector. This port supports 3-wire RS-232 communications with
optional capability for software XON/XOFF handshake for pacing communications.
By default the COM port also provides diagnostic output during boot and
serves as a serial access point to the Command Line Console. This port is
available for connection to remote equipment.
In connecting a remote serial device it is recommended that you first use
the
AUX port. The AUX port is by default dedicated to application use; It
is supported by IOLOG providing comprehensive transmission logging; It
provides no unexpected output such as diagnostics; And, there are additional
communications lines and communication modes.
NOTES
The MODE -S command can be used to silence diagnostic output and to disable
access to the Command Line Console. The Boot Dialog may also be disabled
through the WebUI under the Serial I/O Configruation tab.
