Make use of the keystroke configure option and the -I commandline option of DOSEMU (>=dosemu-0.66.2) such as
dosemu.bin -D-a -I 'keystroke "dir > C:\\garbage\rexitemu\r"' |
The "..." will be 'typed in' by dosemu exactly as if you had them typed at the keyboard. The advantage of this technique is, that all DOS applications will accept them, even interactive ones. A '\' is interpreted as in C and leads in ESC-codes. Here a list of of the current implemented ones:
\r Carriage return == <ENTER>
\n LF
\t tab
\b backspace
\f formfeed
\a bell
\v vertical tab
\^x <Ctrl>x, where X is one of the usual C,M,L,[ ...
(e.g.: \^[ == <Ctrl>[ == ESC )
\Ax <Alt>x, hence \Ad means <Alt>d
\Fn; Function key Fn. Note that the trailing ';' is needed.
(e.g.: \F10; == F10 )
\Pn; Set the virtual typematic rate, thats the speed for
autotyping in. It is given in unix timer ticks to wait
between two strokes. A value of 7 for example leads to
a rate of 100/7=14 cps.
\pn; Before typing the next stroke wait n unix ticks.
This is useful, when the DOS-application flushes the
keyboard buffer on startup. Your strokes would be discarded,
if you don't wait.

When using X, the keystroke feature can be used to directly fire up a DOS application with one click, if you have the right entry in your .fvwmrc
Make a file "FILE" containing all keystrokes you need to boot dosemu and to start your dos-application, ... and don't forget to have CRLF for 'ENTER'. FILE may look like this (as on my machine):
2^M <== this chooses point 2 of the boot menu
dir > C:\garbage^M <== this executes 'dir', result to 'garbage'
exitemu^M <== this terminates dosemu |
(the ^M stands for CR)
execute dosemu on a spare (not used) console, maybe /dev/tty20 such like this:
# dosemu.bin -D-a 2>/dev/null <FILE >/dev/tty20 |
This will _not_ switch to /dev/tty20, but silently execute dosemu and you will get the '#' prompt back, when dosemu returns.
I tested this with dosemu-0.64.4/Linux-2.0.28 and it works fine.
When your dos-app does only normal printout (text), then you may even do this
# dosemu.bin -D-a 2>/dev/null <FILE >FILE.out |
FILE.out then contains the output from the dos-app, but merged with ESC-sequences from Slang.
You may elaborate this technique by writing a script, which gets the dos-command to execute from the commandline and generate 'FILE' for you.
When you try to use one of the above to start dosemu out of a crontab, then you have to asure, that the process has a proper environement set up ( especially the TERM and/or TERMCAP variable ).
Normally cron would setup TERM=dumb, this is fine because DOSEMU recognizes it and internally sets it's own TERMCAP entry and TERM to `dosemu-none'. You may also configure your video to
# dosemu.bin ... -I 'video { none }' |
# dosemu -dumb |
