RUNNING DOS COMMANDS
Pressing Alt-J will let you jump to a DOS shell. You will see
the DOS prompt and will be able execute any DOS command, for
example 'dir'. If there is enough memory left, you can even
run programs. To exit the DOS shell type 'exit' and press Re-
turn. You will be back in Telix with the screen undisturbed
from before your jump to the shell. In order to run the DOS
shell, there must be enough memory left, and Telix must be
able to find the file called COMMAND.COM. If either of these
requirements is not met, Telix will tell you so. (The file
COMMAND.COM is the DOS command interpreter. It is usually
pointed to by the DOS environment variable COMSPEC. See your
DOS manual for more information). If you run a serial port re-
lated program in the shell, there is a good chance that it
will re-initialize the com port and another piece of informa-
tion called the com interrupt vector. If this happens, Telix
will notice and re-initialize the port to the old values when
you return from the shell.
