10.10.1 Serial Talk Through and Comms Watch
The options do not have a timeout when connected in terminal mode via PakBus.
Otherwise P: Serial Talk and W: Comms Watch ("sniff") modes, the timeout
can be changed from the default of 40 seconds to any value ranging from 1 to
86400 seconds (86400 second s = 1 day).
When using options P or W in a terminal session, consider the following:
•
Concurrent terminal sessions are not allowed by the CR800.
• Opening a new terminal session will close the current terminal session.
• The CR800 will attempt to enter a terminal session when it receives non-
PakBus characters on the nine-pin RS-232 port or CS I/O port, unless
the port is first opened with the SerialOpen() command.
If the CR800 attempts to enter a terminal session on the nine-pin
RS-232
port or
CS I/O port because of an incoming non-PakBus character, and that port was not
opened using the SerialOpen() command, any currently running terminal
function, including the comms watch, will immediately stop. So, in programs
that frequently open and close a serial port, the probability is higher that a non-
PakBus character will arrive at the closed serial port, thus closing an existing talk-
through or comms watch session. If this occurs, the FileManager() setting to
send comms watch or sniffer to a file is immune to this problem.

10.12 Troubleshooting — Data Recovery
In rare circumstances, exceptional efforts may be required to recover data that are
otherwise lost to conventional data-collection methods. Circumstances may
include the following:
•
Program control error
