OS/2 Warp Communications Questions and Answers
=======================================================================
Please Read Entire Document for Full Explanation of Procedures
--------------------------------------------------------------
DESCRIPTION
Answers to commonly asked questions about OS/2 Warp Communication
issues.
RESOLUTION
Question 1
How do I get HyperACCESS Lite to initialize the modem?
HyperACCESS Lite occasionally does not initialize the modem. Put a
check in the XON/XOFF box for sending and receiving. Decreasing the
baud rate from 14400 to 9600 might allow the modem to initialize.
Question 2
What class does a US Robotics modem need to be set to in FaxWorks?
A US Robotics modem should be set to Class 1 type modem.
Question 3
I am having a problem with Internet Access. What should I do?
You can connect to the Internet using either the IBM Internet Dialer,
in the IBM Internet Connection for OS/2 folder, or the Dial Other
Internet Providers, in the Internet Utilities folder. For information
on Configuring the "Dial Other Internet Providers" application,
call 1-800-IBM-4FAX and requested document #5597.
Question 4
I am receiving a SYS1059 under OS/2 Warp with Pen for OS/2. How can I
resolve this?
If you receive the error message SYS1059 while installing Pen for OS/2,
look to see if the mouse statements are installed and configured
properly in the CONFIG.SYS file. Refer to the OS/2 Warp README file
for further instructions for Pen for OS/2.
Question 5
During OS/2 startup, I get a SYS1201 error as the COM.SYS driver is
loaded. How can I correct this error?
To correct a SYS1201 error flagged by the COM.SYS statement, check
for multiple COM.SYS statements in the CONFIG.SYS file. Delete any
duplicates. Be sure that the COM.SYS driver file is located in the
\OS2 directory.
Question 6
The MODE command seems to work on my system, but applications
can't find my modem. Is there something wrong with the modem?
If your modem's function is in question, at an OS/2 command prompt
type, in all capital letters:
ECHO ATA > COMX:
where X is the COM Port number that the modem is connected to.
You should hear the computer pick up the phone and try to answer.
If this does not occur, there could be a hardware configuration problem.
If you suspect a hardware problem, contact your modem vendor
for support.
Question 7
I accidentally deleted the Internet Connection folder. How do I
re-create it?
With all of your Internet components installed within the Internet
Connection folder, recreating the icons could become awkward in the
case of accidental deletion. To help you recover the folder (while
leaving the existing data intact), OS/2 Warp provides a program called
IFOLDER.EXE. To execute the program: Open an OS/2 Window from the
Command Prompts folder and type IFOLDER. The icons should reappear.
In some cases, the icons may not work properly after you restore them.
Another utility program, called MAKEIDX.EXE, may help restore their
proper function. MAKEIDX requires a path name to your UltiMail Lite
directory, mail login name, and password as in the following sample
command:
MAKEIDX d:\TCPIP\UMAIL\MAILSTOR\username password
Question 8
Why does my Internet connection drop intermittently?
Your modem may be outpacing your computer's ability to handle incoming
data, particularly if you're using a 14.4 or 28.8K bps (bits per
second) modem. The problem is usually due to older technology serial
chips (called UARTs) in the computer, which can store only one incoming
character at a time in their buffers. Newer UARTs generally store
between 16 and 32 incoming characters; this higher capacity is
important in a multitasking system that may be busy doing something
else while modem data is coming in.
You can check your UARTs buffering capabilities by opening an OS/2
Window from the Command Prompts folder and typing the following
command:
MODE COM2
where COM2 is the serial port for your modem (it might actually be
COM1, COM3, or COM4). In the report produced by the command, look
for the command that reads BUFFER=. If you see BUFFER=N/A, the UART
is an older model without the buffer. Otherwise, the statement should
read BUFFER=ON or BUFFER=OFF.
If you want to replace your serial ports with newer, buffer-equipped
models, look for adapters that have either 16550 (16-byte buffer) or
16650 (32-byte buffer) UARTs. You must either disable the existing
serial ports (see your computer's hardware documentation) or enable the
new ports for different addresses (such as COM3 and COM4).
A buffer is a small area in memory where a device (such as a
communications port or disk drive) can store
data while waiting for the computer to retrieve the data. This allows
the device to continue its operations while the computer is busy with
another device or task.
