I tried to use the SZ zmodem on unix to send a file to my PC, I always get Some CRC error in the very begining, about 1.3k. I heard it has something to do with the NetWork(CDCN) and Xon/Xoff. I can always turn off Escape code and make it work, but It would be much slower. Can anyone help me, Either tell me how do I change the Terminal Setting on the Vax or Suggest a better protocol. Thanks.

Recent ZMODEM extensions allow individual control characters
to be escaped. I am testing new versions of VMS rz and sz
which will support some of the ZMODEM-90(TM) extensions; they
are available on TeleGodzilla's upgrade/vms subdirectory.

Try using the -l option of zmodem, like this: $ sz -l 512 <your_file> If 512 doesn't work try something smaller or larger. I have had success with 512 and I still get good "efficiency," better than KERMIT. The XON/XOFF isn't necessarily coming from the VAX, it could be the answering modem (assuming you are dialing in). -- John Palkovic (708) 840-3527 palkovic@fnal.bitnet,palkovic@linac.fnal.gov University of Wisconsin-Madison {yclept,tellab5,obdient}!linac!palkovic & Fermilab, Batavia, IL Coor: 41 50 16 N / 88 15 46 W
