6.1.2.3.2 Computer Networked
Within a particular computer network (Ethernet), each Windows NT workstation must have a unique “computer name.”
Therefore (if the console/computer is networked), its computer name must be changed from the factory default computer
name stated above.
To avoid confusion by easing console/computer identification, it is recommended each C3 Maestro console for
Windows NT workstation be given a descriptive computer name that identifies, at a minimum, the switch assignment number
of the CEC/IMC which it is connected to and its own console (CIM) assignment number. For example, assume the console is
connected to IMC 32 via CIM 3 in the IMC; a good name for this workstation is “IMC32CON03”. Naming should be
consistent between all console workstations with a domain. Naming the Windows NT workstations in this manner will ease
configuration and maintenance personnel duties, especially, if/when configurations are performed across a network. Refer to
The Windows NT on-line help or the Windows NT Workstation Installation Guide and/or System Guide manual for complete
details on computer naming.
6.1.3 Verifying FIFO Is Enabled On COM1 Thru COM3
Each serial communication port which supports console operation has a very important configuration setting—“first-in-
first-out” (FIFO)—which, if not enabled, may cause erratic operation. Some third-party software installation programs may
disable FIFO on one or more COM ports. In addition, changes within Control Panel’s Ports dialog box may unintentionally
disable FIFO. Verify FIFO is enabled for COM1 thru COM3 as follows:
1.
From Windows NT Program Manager, if necessary open the Main program group by double-clicking on its icon:
2.
Open Control Panel by double-clicking its icon:
3.
Execute the Ports program within Control Panel by double-clicking on its icon:
4.
If necessary, from the Ports dialog box select COM1: in the Ports: listing.
5.
Select <Settings…> and then <Advanced…>. The Advanced Settings for COMx: dialog box will appear
(where x = selected COM port number).
6.
Verify the FIFO Enabled check box is checked.
If not, check (enable) it
.
7.
Exit (return to the Ports dialog box) via two <OK> command button clicks. Based on past experience, <Cancel> is
not recommended here, even if no changes of any sort were required within the Advanced Settings dialog box. If a
change was made, a prompt will appear noting that Windows NT must be restarted. Do not restart at this time.
8.
From the Ports dialog box, select COM2: in the Ports: listing.
9.
Repeat steps 5 thru 7 for COM2.
10.
From the Ports dialog box, select COM3: in the Ports: listing.
11.
Repeat steps 5 thru 7 for COM3.
12.
If a change was made in step 6 (for COM1, COM2 and/or COM3), restart Windows NT at this time.
Since the console application automatically overrides other serial port settings established within the Ports program such
as baud rate, number of data bits, etc., no other COM port setting changes are required via the Ports program.
