Connection Methods, Attributes
and Configurable Features
This chapter describes:
• Connection methods, which are configured for each serial port
• Attributes, which are configured for each serial port
• Configurable features, which are enabled/disabled for the entire hub
Serial Port Connection Methods
There are several methods to access a serial port on an ESP hub.
• Serial port redirection - see page 16
• Telnet server - see page 16
• Raw TCP server - see page 17
• Raw TCP client - see page 19
• Modem emulation - see page 21
• Configuration utility - see page 28
You may configure port connection methods using any of the available tools.
• Web interface - see Displaying or Changing Port Connection Methods on page 33
• Configuration utility - see Displaying or Changing Connection Methods on page 46
• Configuration file - see Port Connection Method Commands on page 57
Exclusivity and restrictions
Each connection method may be enabled or disabled for each ESP port. A port may have multiple
connection methods enabled, with the following exceptions.
• The raw TCP client connection method is exclusive; when it is enabled on a port, no other con-
nection methods can be enabled for that port. (Conversely, if other connection methods are
enabled for a port, you cannot enable the raw TCP client connection method on that port until
you disable the other methods.)
• If you enable the raw TCP server connection method and enable the idle TCP buffering option
on a port, then the TCP server connection method becomes exclusive; no other connection
methods can be enabled for that port.
