ESP Serial Hub Installer/User Guide
File Format and Command Syntax
Configuration files must conform to the following conventions:
•
Each command must begin on a new line.
•
Command words are not case sensitive.
•
Parameters are separated by one or more spaces.
•
Parameters with values that enable or disable connection methods or features use a space
between the keyword and the value. For example:
port 2 tcpserver enable monitordcd enable ipviadhcp disable
•
When enabling/disabling a connection method, the Enable or Disable keyword must be the
first parameter specified after the connection method name. Additional required or optional
parameters may appear in any order following the Enable or Disable keyword.
For example, both of the following commands will result in the same connection method
configuration for port 1.
port 1 telserver enable localipport=2000 timeout=400 buffering=10000
port 1 telserver enable buffering=10000 localippoprt=2000 timeout=400
•
Parameters that include an equal sign and a value (for example Parity=Even) may not contain
embedded spaces.
•
If you want to enable a connection method that is mutually exclusive of other connection
methods, and one or more of those other methods was enabled previously (either earlier in this
or another configuration file, or through another tool such as the web interface or configuration
utility), you should expressly disable the other connection method in the configuration file
before enabling the mutually exclusive method.
For example, if you want to enable the modem emulation connection method on a port that
currently has the TCP client connection method enabled, you must first disable the TCP
client method:
port 1 tcpclient disable
port 1 modem enable . . .
•
In commands that require a port number, you may specify
want the command to be applied to all serial ports on the hub. If you specify
Interface command, the operation will be applied to all multi-interface serial ports (all ports on
an ESP-2 MI, ESP-4 MI or ESP-8 MI hub; ports 1-8 on an ESP-16 MI hub).
•
If an optional parameter is not specified in a command, its value remains as is.
The command syntax in this manual uses the following conventions:
•
Variables are shown in italic type surrounding by angle brackets (< >).
•
Choices are separated by a vertical bar (|).
•
Optional parameters are enclosed in brackets ([ ]).
