Data Capture Causes TinyTERM 4.04 to Crash

Tuesday, February 27th, 2007

Turning on data capture in TinyTERM 4.04 will cause it to crash and close, unless the Status Bar is turned off. To do that, go to the View menu and uncheck the “Status Bar” option.

The crash is caused by a bug in the butterfly net graphic that normally displays in the status bar. Other versions of TinyTERM do not have this problem. There is no patch available.

Can’t Enter a Line Turnaround Character

Tuesday, February 27th, 2007

In the Session Properties for TinyTERM version 4.x, on the Session tab, there is a Setup button for the terminal emulation type. Clicking that brings up the “Emulation Setup” dialog.

The first line in that dialog is “IBM 3101/3151 turn around character.” In most cases this should be set to 13 (the ASCII value of the carriage return character) for the function keys in the IBM3151 emulation to work correctly.

TinyTERM version 4.04 will only accept a single digit in this field. To set it properly, you will need to edit your .tpx file manually, using Notepad or another text editor. Search for the line:

TurnChar=

Edit that to add the number 13 to the end of the line:

TurnChar=13

Save the changes and exit. If you open the “Emulation Setup” dialog after this and save any changes, you will need to make this manual edit again.

Dialling the Modem Manually

Tuesday, February 27th, 2007

There may be times when you want to dial out by typing commands, rather than allowing TinyTERM or TERM to connect the modem automatically. To do this, configure TinyTERM to connect to the serial port your modem is attached to.

If it’s an internal modem, it will still be associated with a serial port. Check your operating system documentation for help locating the appropriate port.

Once connected, type

AT

and hit Enter. You should see an OK message come back. If there’s no response, or if you can’t see the letters you typed, try this command:

ATE1Q0

Most modems will respond to this with a clearly visible OK. You can then type the ATDT command to dial the modem, followed by the phone number. For example:

ATDT1-801-268-3088

The AT commands are all part of the Hayes modem command set. Most modems will accept them readily. For a complete list, see http://www.modemhelp.net.

Dialing a Modem with a Calling Card

Monday, February 26th, 2007

TinyTERM and TERM can dial a calling card, then enter an access code before dialing a modem number. You simply need to enter the entire calling sequence as the phone number, using commas to pause the dialing for two seconds each.

For example, suppose I need to dial 1-800-555-5555 to access my calling card. Six seconds later, it connects and asks for my PIN, which is 1111. Four seconds after that, I can dial the number I need, 801-268-3088. I would enter that number like this:

1-800-555-5555,,,1111,,801-268-3088

This assumes I don’t need to dial 1 for the actual number when using my calling card. You don’t actually need the dashes in the phone numbers, either. They’re ignored when dialing, but they do make it easier to read.

Line Draw Prints as Characters

Monday, February 26th, 2007

When printing a screen in TinyTERM 4.03, lines will sometimes print as odd characters instead. This is corrected with this patch, through the implementation of multiple code pages for printing. Installation instructions and documentation are in this document. TinyTERM versions 4.04-4.12 incorporate the patch.

The problem was reintroduced in TinyTERM 4.13 with the Use printer fonts option in the new Printer Setup dialog. The same thing happened printing direct to device. This was fixed in TinyTERM 4.21.

Fonts Display Too Close Together

Monday, February 26th, 2007

TinyTERM 4 automatically adjusts its font size for the number of lines and columns required in the available space. The default TERM font is a bitmapped font, though, which means sometimes the letters don’t fit smoothly into their spaces. They appear to overlap or just display too close to each other. There are a few ways to improve this:

  1. Change the size of the available window space. The easiest way to do this is to resize the TinyTERM window. But if the window is already maximized, there are still things you can do.
  2. Turn the tool bars on or off. From TinyTERM’s View menu, you can turn on or off several items:
    • Ribbon Bar, the buttons across the top of the window
    • Status Bar, the line of indicators at the bottom of the window
    • Menu Bar, the standard Windows menu items at the top
    • Session Bar, the session buttons just above the Status Bar
    • Address Bar, which shows the connection address (this is automatically turned off when you turn off the Ribbon Bar)
    • Vertical Scrollbar, which is available on the right side in some versions of TinyTERM
  3. Change the display font. To do this, open the Session Properties and go to the Fonts tab. Click on the Term font to highlight it, then click the Down button once to make it second in the list. TermCS1 will move to the top. It’s a TrueType font, so it scales much better to different window sizes.

TinyTERM 4.31 and higher also have improved font scaling, particularly in 132-column mode.

CR 352, font cut off on right at TinyTERM start
CR 682, Ribbon Bar must be on

Multiple Sessions Bleed into Each Other

Monday, February 26th, 2007

If you have multiple sessions open in a single TinyTERM window, you may see information from a hidden session “bleed” into the active session. There are two causes for this.

  1. Your Windows video driver needs to be updated. Contact the video card or PC manufacturer for an updated video driver.
  2. One of the background sessions updates the screen regularly. When this happens you can see the updates in any active session, not just the correct one. This was corrected in TinyTERM 4.10.

The Euro Symbol

Monday, February 26th, 2007

The euro symbol € was added to the TERM font in TinyTERM 4.20. In earlier versions, you will need to use a different font to display that symbol.

To add a font to TinyTERM, open the Session Properties and go to the Fonts tab. Click the Add font button. Select the font you want to use, then click OK to add the font to TinyTERM’s list.

To make the font primary, click on it in the font list to highlight it. Then click the Up button repeatedly to move it to the top of the list. TinyTERM will then display text using that font first.

Blank Screen After Installing TinyTERM

Friday, February 23rd, 2007

When you start TinyTERM right after install, the screen can be completely blank. This most often happens when an earlier version of TinyTERM was installed on the PC, but not completely uninstalled. The existing fonts interfere with the install of the new fonts, causing the display problem. Restarting the PC will fix it.

TinyTERM Closes on a Connection Error

Friday, February 23rd, 2007

When you start TinyTERM, if there’s something wrong in the connection settings, you’ll get an error message. If TinyTERM closes after you click OK on the message, it means TinyTERM is set to close automatically on disconnect. A connection error is handled like a disconnect.

To fix the problem, use Notepad to edit the .tpx file you’re using with TinyTERM. Search for the line:

closedisc=1

Change the 1 to a 0 (zero):

closedisc=0

Save the changes and exit Notepad. The next time you start TinyTERM, you’ll still get the connection error. However, TinyTERM won’t close, so you can fix the connection settings. You can then set the Close session on disconnect and exit option once you know the connection is working properly.

Century Software, Inc., has been asked to change this behavior, so that connection errors don’t trigger the “close on disconnect” behavior. This is problematic, as a Winsock error includes a disconnect event. So this enhancement has not yet been added.
