Poll timeout
The serial port connection will close if the polling sequence did not complete
within the specified amount of time. Checking this option will automatically check
the “Close if poll timeout” option on the “Polling” tab and vice-versa. If you check
this option you must also fill in the poll timeout value on the “Polling” tab.
Available on all serial ports.
Network timeout
Close the serial port connection if the network peer fails to respond. The network
peer is identified either by the remote host and TCP port number on the “Opening”
tab or by the IP address given in the ADTD command if the modem emulation
software is active on this serial port.
Available on all serial ports.
Timeout (ms)
This field may be filled in when “Network timeout” is checked. It is the number of
milliseconds that may elapse while waiting for a response from the network peer.
Available on all serial ports.
Close delay (ms)
After one of the above conditions is detected, delay by this number of ms before clos-
ing the connection. The close condition must persist over this time interval, otherwise
the connection remains open.
Reopen delay (ms)
Delay before reopening, after a close. Specify the number of milliseconds to wait after
a connection request is made before action is taken.
Set this to at least a few thousand ms to prevent excessive network traffic in the case
that something is misconfigured, e.g., the connection gets a close condition immedi-
ately after opening.
