This readme file provides instructions for using the DigiBoard OS/2
Serial Port Test Utility, DGOS2UD.EXE. This utility tests any OS/2
Serial Device supported by a Physical Device Driver.
Hardware and Software Requirements -
Asynchronous Serial Port product.
OS/2 Device Driver for the product (loaded).
DGOS2UD.EXE Utility program.
Single port loopback connector wired as such :
Signals DB-25 pins
Rx -> Tx 2 -> 3
DTR -> DSR, DCD 20 -> 6,8
RTS -> CTS, RI 4 -> 5,22
Test Preparation -
To prepare for testing a serial port, ensure that the following
criteria are met :
- The hardware to be tested is properly installed.
- The correct device driver has loaded successfully.
- The loopback test connector is firmly installed on the port's
connector or cable.
- The DGOS2UD.EXE utility is accessible from your hard disk of floppy
drive.
DGOS2UD Execution -
To start the utility, simply type DGOS2UD from any OS/2 Full Screen
or Window. You will see a menu from which you can make the following
choices :
Select Port
Short Test
Continous Test
Display Error Log
Log File
Exit
Each of the choices are described below :
Select Port -
This selection permits you to specify the Serial Port to be tested
by specifing the port's name. The default name is COM3 since you may
very likely have the DigiBoard port's starting with this device name.
If this is not the case, you may simply enter a different name.
Short Test -
Selecting this option starts testing the serial port by running
a series of tests that will terminate after one full pass. These
tests check that all modem control outputs and inputs function
properly. Data transmission and reception is also test at different
combinations of baud rates, data bits, stop bits, and parity bits.
At each combination, 10 bytes are transmitted and checked for correct-
ness after reception. Also, the port is tested at it's maximum baud
rate with transmission of 10 kilobytes of data.
The baud rates tested are as follows :
110,150,300,600,1200,1800,2400,4800,9600,19200,38400,57600 and
115200 with the following exceptions :
Product Highest Baud Rate
Non-Intelligent Serial Ports (e.g COM2) 19200
DigiBoard's PC/X Boards 19200
DigiBoard's COM/Xi Boards 19200
DigiBoard's C/X Concentrators 57600
The baud rates are limited due to product capabilities.
Continuous Test -
This test is just a continuous cycle of short test executions.
When you select this option, you may choose wether the test will
stop when an error is encountered or just continue testing until
you manually stop it.
Display Error Log -
This selection allows you to view the record of errors for the
test just executed. The error log records the following types of
errors :
Receive Errors - These errors indicate that not all the data
was received.
Transmit Errors - These errors indicate that not all the data
was transmitted.
Data Integrity Errors - These errors indicate that the received
data was incorrect.
Receive Overrun Errors - These errors indicate that the hardware
lost receive data.
Receive Queue Overrun Errors - These errors indicate that the
driver did not have enough buffer space to store the
received data.
Parity Errors - These error indicate that the hardware detected
a parity error on a received byte.
Framing Errors - These error indicate that the hardware detected
a framing error on a received byte.
Modem Signal RTS/CTS Errors &
Modem Signal DTS/DSR Errors - These errors indicate a failure
occured with the indicated modem control line pair.
Log File -
This option allows you to enable or disable the logging of data
transmission errors to a disk file in your current directory. This
error file has the name PORT#.ERR, where # is the com ports number
(e.g. 2 for COM2). The errors are appended to the log file with a
time/date stamp and a record of the erroneous data.
Exit -
Select this option to exit the utility.
Error reporting -
During the Short Test or the Continuous Test with Stop On Error
selected, all errors will be presented to you in a red error message
box with a description of the error and the test parameters. If you
are running Continuous Test with no error stops, ann error indication
will be posted at the bottom of the screen.
Pass Indications -
If your port has passed the diagnostic tests, there will be no
errors reported in the Error Log and you may assume that the
hardware and driver are functioning properly.
