Error 4555 on Thinkpad

Thursday, April 26th, 2007

This error has only been seen on the IBM Thinkpad T21 using an IBM 10/100 Ethernet Mini-PCI Adapter with 56k Modem (MiniPCI Combo), running on Windows 2000. Any attempt to use TAPI in TinyTERM gives, “Error (4555) Get property ‘IsConnected’ failed: Invalid object instance.”

No other TAPI-using application gives an error. Updating the modem drivers does not work. However, connecting directly to the COM port and dialing the modem manually works.

ASCII Data Capture Traps Non-Printable Characters

Thursday, April 26th, 2007

When you configure TERM or TinyTERM for ASCII format data capture, it captures and writes to file every character in the ASCII range 0-255. This includes control characters such as ^T and the escape character. There is no way to prevent this behavior.

Word XP Documents Open Slowly

Thursday, April 26th, 2007

On a system with Microsoft Word XP installed, configure TinyTERM for a modem connection. Once TinyTERM has dialed in, open a Word document. This takes several minutes to complete, or completes as soon as TinyTERM hangs up. It doesn’t matter if you double-click the file, or if you use Word’s File menu to open the document.
This does not happen with serial or network connections.

Code Pages

Thursday, April 26th, 2007

Code pages determine which characters are sent when a keyboard key is pressed, and which ones are displayed when data is received. TinyTERM has over 50 which will cover most Western languages, plus Unicode support for Chinese, Japanese, Korean and UTF-8.

More information is available in the TinyTERM Help. Go to the “Reference” section of the Contents, then to the “Code Page Reference.”

Ignore Host Cursor Changes

Wednesday, April 25th, 2007

Most terminal emulations allow the host to change the cursor: from a block to an underscore, from blinking to solid, etc. TinyTERM 4.x can ignore text color changes triggered by the host, but not cursor changes.

TVI925 and TVI950 Ignore Keyboard Lock Sequence

Wednesday, April 25th, 2007

When using TVI925 or TVI950, there is an escape sequence that will lock the keyboard: \033#. To unlock the keyboard, the sequence is \033″.

In TinyTERM 4.x, these sequences are ignored. The user can continue to type, even when the keyboard should be locked.

TERM in Background Doesn’t Answer Modem

Wednesday, April 25th, 2007

On a UNIX system, disable getty on a modem port. Then run a TERM script that does an answer wait on the modem. The script should continue to execute when someone dials into that modem.

When you run this script in the background using the ampersand character:

term modemscript.cmd &

the script never answers the modem, even if the script works properly run without the & switch. The TERM process runs, but it does not answer the modem.

Highlight Text During Scrollback

Wednesday, April 25th, 2007

By scrolling back through the session buffer, you can view text that would otherwise be gone. But you cannot highlight more than one screen for copy operations. There is no way to select text across both the current screen and one in the scrollback buffer at the same time.

To work around this limitation, turn on data capture before scrolling starts. The entire session will be saved to the capture file. You can then get the screens you need from that file.

Trailing Spaces Copied

Wednesday, April 25th, 2007

When you copy text from the TinyTERM window, trailing blank space you may have selected gets copied as spaces. For example, if you select a block of text that looks like this on screen:

Copy the text from
TinyTERM emulator
into the Notepad.

the second and third lines are padded to the length of the first with spaces.

This is due to the way TinyTERM displays text. Each character on screen has its own “cell.” When you select a block of text, you’re actually highlighting a set of cells. Those that have no text in them are treated as spaces. So when you paste the text into any application, those spaces get pasted as well.

TN5250 Does Not Update Database

Wednesday, April 25th, 2007

This problem was first defined in a customer application. In one of the database screens, F1 should update the database with the information contained in the fields on the screen, then notify the user of the change. In TinyTERM Plus it does not update the database, but still indicates that it has been changed. F1 works properly everywhere else. This particular data entry screen does a callback to the emulator to update the screen. TinyTERM Plus does not handle it correctly.

CR 179, fixed in TinyTERM Plus 4.53
