Does anyone have a Unix version of zmodem that supports 7 bit transmission? The local network which I use to access the university's computers uses a 7 bit even parity protocol. The only file transfer protocol that I have found that works is kermit. My PC documentation for zmodem (DSZ.EXE) specifically refers to two flags (-E, -P) that use 7 bit transmission. However, the unix docs do not discuss this feature and all attempts to get it to work have failed. I have checked rzsz0525.zoo and rzszv307.zoo. Is there a more recent version or a different one that supports the PC 7 bit feature? Does anyone have any experience getting this to work? Is there an alternative protocol that supports 7 bit transmission on both a PC and a Unix system that I can substitute? Thanks in Advance, Dani Climan climan@128.2.242.52 or climan55@wharton.upenn.edu

Zmodem has supported the -e option for as long as I've used it. You need to use the -e on the transport side, i.e. with 'sz -e' and not with rz. -- Tin -- .---------------------------------------------------------------------- .

I have no plans to upgrade the shareware rzsz files to include ZMODEM-90
(MobyTurbo, 7-bit, etc.). I learned my lesson with rzsz version 3.x.
Unix Professional-YAM replaces rz and sz with hard links to /usr/bin/yam.
This provides the full ZMODEM-90 feature set.
