- Hi, everyone!
-
- I am not sure that this is appropriate group for my posting, but
- only here I've found couple articles about ZMODEM.
-
- I need to transfer data files from our UNIX (SunOS) environment to the
- customer's PC. I've successfully did it with KERMIT, but it require some
- user action to initiate receive operation.
- So, my customer prefer to have ZMODEM, to do nothing.
-
- I've downloaded source code (zmodem.3.14.tar.Z), unpacked it and built
- without problems using included makefile. (I issued 'make bsd' because
- we are running SunOS 4.1.2).
- Problems starts when I am trying to send files - plain ASCII text.
- I am executing
- sz -ay <filename>
- and it definitely starts working, because PROCOM+ on the PC side popup
- ZMODEM window and tries to receive data. But all the times I am getting
- "BAD CRC" message. If data file is short ( <5K ) it sometimes goes through
- after 10-15 retries, but bigger files - never.
- I tried to play with flags for sz (i.e. use 32- or 16-bit CRC and so on)
- as well as manipulated with ZMODEM options within PROCOM, but always get
- same result.
- I cannot blame telephone line, because KERMIT works perfectly. Also I've
- tried ZMODEM with several BBS and it also work fine, so I can't blame PROCOM
- either.
- It definitely something wrong with our UNIX site. May be I am doing something
- wrong, or there are problems with public domein version.
-
- If somebody could give me a hint I would very appreciated.
- IG.
-
- BTW. I have INTEL 2400EX modem on the PC site and NEC N9635E on the UNIX site.

- el EOL marks (default is NULL)
- du make a call flag (dial up)
- pn phone numbers (@ =>'s search phones file; possibly taken from
- PHONES environment variable)
- at ACU type
- ie input EOF marks (default is NULL)
- oe output EOF string (default is NULL)
- cu call unit (default is dv)
- br baud rate (defaults to 300)
- fs frame size (default is BUFSIZ) -- used in buffering writes
- on receive operations
- tc to continue a capability
