Troubleshooting
Problem: How do I run a 4010 program?.
Solution: Display the Emulation Settings dialog box and select Tek as the emula-
tion, then display the Dialog Settings dialog box and set the Dialog
Area Enabled option to 0 (zero).
Problem: The text background colour is incorrect.
Solution: Select the required text colour indices in the Attributes dialog box then
display the Dialog Settings dialog box and select Dialog Indices
Locked.
Problem: The Gin cursor is too small.
Solution: TeemTalk displays a small crosshair cursor by default. You can change
the size of the cursor by using the following initialization file command
or command line option:
Initialization file command: CrosshairSize=1-4096
Command line option: -x1-4096
Problem: The position of text is incorrect and/or the wrong line is displayed
when scrolling through the text.
Solution: Try changing the setting of the Cursor Origin option in the Dialog
Settings dialog box.
Problem: Characters are being lost over serial interfaces.
Solution: The problem is a result of a data overrun in the serial I/O controller on
the communications board of the PC. As characters are received from
the outside world, the serial I/O controller stores characters received
over the RS232 and then generates an interrupt to DOS to signify the
arrival of a character. DOS, and subsequently Windows then read this
character and pass it to the interested application. The problem comes if
characters are received faster than they can be processed by the PC.
Most serial controllers use a buffering technique which stores multiple
characters during times of peak loading so that the affect is minimised.
Because Windows and other applications disable processing of inter-
rupts for considerable periods of time, this buffering is not always
sufficient to overcome the problem. Below are some suggestions to
minimize the problem.
1. Edit the CONFIG.SYS file so that the stacks statement (if one exists)
reads STACKS=0,0. If this isn't done, DOS will turn interrupts off for
a short period when there is a hardware interrupt.
