set/checked automatically (must be enabled) or
manually. Second message is from the
datalogger indicating its clock was changed but
that no program is running, i.e., no program
(.DLD file) has been downloaded. Third
message, also from the datalogger, indicates its
clock was changed and there is a program
running. There is no response generated when
the clock is checked. Clock changes are
logged in CLKSET$.LOG files. See Section 8 in
the RTMS manual.

This warning usually occurs when the
datalogger clock is changed so an output
interval is missed. It indicates that a gap
occurred in the time stamps of the records from
the tables. The record numbers of the records
will not have a gap.

A datalogger program was downloaded to
datalogger. If the datalogger can compile and
use program, the second message is returned
from the datalogger. If the datalogger receives
the program but cannot compile it due to an
error, it will return a message like the third
message (E22 indicates a missing END
statement). The last fault messages indicates
that the datalogger received the file but did not
recognize it as a datalogger program.

The first message indicates that the device the
DlsMgr (computer) was attempting
communication with did not respond. The
second indicates a received packet failed the
signature test (and was retried usually).
The third packet indicates the DlsMgr received
characters on the serial port when it did not
expect them.
The fourth message indicates the DlsMgr
received an extra response to a command.
These messages are usually not cause for
concern when they occur occasionally as serial
communications are not perfect. When
warnings occur repeatedly and are followed by
fault messages, there is a communication
problem. When this occurs, the following gives
some probable causes:
The first indicates the device is not responding.
See Section 3.0 above.
The second would indicate that characters are
routinely missed. This can mean the OS/2
computer has insufficient resources or too many
programs are being run concurrently. It may
also indicate a bad serial port or device.
The third indicates that the wrong device may
be attached to the COM port and is echoing
characters when it is not expected. For
example a Hayes modem echoes characters
while a MD9 base does not. If the Net
Description incorrectly specifies the COM port
