It'll hang on sending files from ZTerm to the Ultrix host, but downloading from the host has no problems (It's the fastest protocol I've found by far!). The error message is something like "ZRPOS returns zero" and ZTerm will keep retrying. I'm using ZTerm 0.85 and rz 3.00 dated 4-19-89. Any clues? T.C.

The error I'm not real sure about this but a ways back I ran into the same thing. In our case it seemed to me that there was a problem with the UNIX host trying to keep up with the mac (...you know, I'm IN LUV with UNIX - ick! :-). It was a hack but by putting in the pause (effectively converting the Zmodem to Ymodem) for going to the UNIX box seemed to solve the problem. Note also that XON XOFF protocols can muck up the Zmodem stuff too. (Note for Ken...If you haven't noticed, some of our vax ports are 8 bit and some are 7. There is an inconsistency that we need to fix here that we just haven't gotten around to yet :-) give me or Lee Schuler a call and I can explain). -- Jeff Wiseman: ....uunet!tellab5!wiseman OR wiseman@TELLABS.COM

First, check the "Escape Controls" option in ZModem Parms. Some digital switchs or term servers can swallow some control chars and kill any transfer. This option will cause control chars to be sent as a two byte sequence. Also, try putting a multiple of 512 in the Window Size option in ZModem Parms. This puts the protocol into a windowed mode (for send only). 2048 is a good first guess for this option. The message "ZRPOS <number>" is just the receiver saying Hey, I got an error. Please back up to file location <number>. Also, note that some Unix box serial drivers may not be able to keep up with data coming in full bore at 9600 bps. -- Dave -- Z Dave Alverson, Cincinnati & Mason, Ohio Z Address: davea@kgw2.bwi.WEC.COM
