Last December Clem already pointed out that it was popular for file exchange in the Unix scene as well, along with several other similar tools. Also, the ymodem approach to file metadata is very unix oriented, suggesting it originated on Unix or at least that Unix users were an important user demographic. Yet, I could find little trace of x/y/zmodem in the TUHS Unix Tree. The search tool finds it in 2.11BSD, in Minix 1.5 and 2.0 and in V10. Kermit is in those as well, and in 4.3BSD and 4.4BSD on top. have a look at tuhs/Applications/Shoppa_Tapes/usenix878889.tar.gz usenix87/Comm/ usenix89/Comm/ also appears in 386bsd/othersrc/public/zmodem-3.03/ where the license was changed to prohibit commercial use after the RLE changes in April 1989 https://www.ohse.de/uwe/software/lrzsz.html is derived from an earlier version with the license changed to GPLv2
