Shameless plug: I also wrote a tool similar to com2txt in 1996: https://github.com/pts/pts-xcom . A quick comparison:

* com2txt.exe is 7110 bytes long, xcom.com is only 401 bytes long.

* xcom.com can also convert back from text to binary.

* xcom.com can also convert to data text (without the self-decoder header).
