- Hello,
- I installed the Zmodem on our DECstation running
- Ultrix 4.2 . I use ProComm 2.4.2 on my PC .
- The Zmodem contains Ymodem, so I use the Ymodem in
- ProComm to transfer the files DECstation <-> PC .
- I can download from the DECstation to PC, but I
- can't upload from PC to DECstation .
-
- I used:
- >sb <file>
- for download
- >rb
- for upload
-
- The message I got is :bad packet .
-
- I tried to debug the source program, the problem
- looks like the crc checking problem and also
- the block number sent by the ProComm does not
- match the one in Zmodem.
-
- Does anyone have such experiences ?
-
- The line setting I use in ProComm is 1200-N-8-1 .
- My PC is an XT.
-
- Possible problem:??
- 1. the ProComm sends 8-bit crc (actually I don't know
- what kind of crc the ProComm is using), while Zmodem uses 16-bit crc
- this will cause crc mismatching.
- But I use the Ymodem when I connect to BBS, without any
- problem .
- 2. the PC is 16-bit, while the Unix is 32-bit
- But why the downloading is alright?
-
-
- Thanks in advance !
