From dbit.com - ibmpc utils - README:
Can be used to capture tape images for Ersatz-11, among other things. Use "st -f scsi6: iget foo.tap" to read the entire tape at SCSI ID 6 into the file "foo.tap", suitable for use with E11's MOUNT command. It can also go the other way, use "iput" instead of "iget" to write foo.tap onto the tape. Fixed block sizes with recordless files are also supported, like what you get with the UNIX "dd" program. I'm ashamed to say this is written in C (Watcom 11.0). It was originally intended as sample code to be supplied to a contractor (otherwise it would have been in assembly language like everything else I do), but it evolved into a utility in its own right. Files are: aspi.c DOS ASPI interface code st.c the utility itself st.h definitions st.lnk linker script Build it with wcc aspi, wcc st, wlink @st (first change the "libpath" lines in st.lnk to point at where the Watcom libraries are on your system, unless you configured your Watcom better than I did).
