For dial-up MTA's, this parameter will be a dynamic parameter stored in the current table indicating the
current node that the MTA is connected to.
6.33 Frame Duration & Timeout
Frame Duration specifies the maximum time allowed for receiving a single frame. If it is set too low,
very long frames could timeout before being fully received.
Frame Timeout specifies the maximum time that an MTA should wait for an acknowledgement before
re-transmitting the frame. Again, if this is set too low, there may be insufficient time for the frame to be
sent and the acknowledgement returned.
Both times are specified in seconds.
6.34 Device Name
This parameter specifies the communication path for the device used by the agent. Many options are
possible for this parameter, some of the main ones are:
• Simple COM port, e.g. COM1
For a real serial port, this defaults to 9600 baud, 8 data bits, no parity and 1 stop bit. This
format should always be used for UPI and UFI devices.
• Advanced COM port, e.g. COM2:19200,7E1
This syntax allows the baud rate, 7 or 8 data bits, No, Even or Odd parity and 1 or 2 stop bits
to be specified.
• COM port with no flow control, e.g. COM2,NOFLOW
Normally, the RTS and CTS serial port lines provide flow control between devices. For some
simple applications, these may not available and this format allows these lines to be ignored.
Note that with some protocols, data overrun may occur if no flow control is available, so this
format should only be used when absolutely necessary.
• Connection to an network address and port, e.g. 192.168.1.1:6001
In this mode, a serial port is emulated using the network connection; for instance, a
connection to a remote system will only be attempted if DTR is asserted locally, and DCD will
be asserted while connected. If the connection is lost, it will be automatically retried.
• Listening on an network port, e.g. LISTEN:6004 or 0.0.0.0:6005
In this mode, a serial port is emulated using the network connection; in this case, the agent
will listen for an incoming connection on the port specified. Again, the connection will only be
accepted if DTR is asserted locally, and DCD will be asserted while connected. If the
connection is lost, the port will automatically listen for a new connection.
• Connection to local network port, e.g. LOOPBACK:6002 or LOCAL:6003
In this mode, a serial port is emulated using a network connection to the local machine; for
instance, a connection to the specified port will only be attempted if DTR is asserted locally,
and DCD will be asserted while connected. If the connection is lost, it will be automatically
retried.
• Parallel Port LPT1,PRINTER
This is only used with a Printer Agent, but is not recommended as it rarely works properly with
most systems.
