Remote Control Commands
All commands are ASCII commands. For Control Commands, the
command is created by pressing and holding the [CTRL] key and the
designated character key simultaneously. For example, to create the
CTRL-A command, simply press the [CTRL] and [A] keys on the
keyboard simultaneously then release both.
When starting an SSH session, the user will be prompted to enter a
username and password. The default username is “admin” and the
default password for this user is “ESL02921”.
Once the Model 7183 Remote SSH session has been initiated,
commands from Table 2 can be entered. Do not press the enter key at
the end of a command. All responses are terminated with a carriage
return (‘\r’) followed by a new line feed (‘\n’).
A note to those programming their own systems to control this switch
automatically: The ASCII Control Commands are represented as the
decimal equivalent of the numerical position of that letter in the
alphabet, which can then be translated to hex. For example, CTRL-A
translates to ‘1’ in decimal or 0x01 in hex, since A is the 1
st
letter of the
alphabet. CTRL-V, on the other hand, translates to ‘22’ in decimal, and
0x16 in hex, since it is the 22
nd
letter of the alphabet.
