- Hello FBB SysOp, 30-May-93
-
- There seems to be some confusion over the use of the program CUT.COM
- which is shipped with the current FBB distribution. I will try to
- explain how it can be used effectively:-
-
- > CUT.COM can be used when an XMODEM file transfer from an FBB phone
- port crashes before the whole file is recovered by the caller.
-
- > After disconnection the caller should save what portion of the
- file he has collected and note the size (in this example let us
- assume that this section will be called PART1.ZIP and is 252198
- bytes long.
-
- > The caller should then reconnect to the sending BBS and again
- request the XMODEM download, but must now specify the byte offset
- from which the transfer should begin. (In our example this will
- be XGET FILENAME.EXT 252198). This will send the remainer of the
- file from the point at which disconnection occurred. Let's call
- this section which is 64768 bytes long, PART2.ZIP.
-
- > With the transfer completed the caller now has the following in
- the download directory:-
-
- PART1.ZIP 252198
- PART2.ZIP 64768
- CUT.COM
-
- > These two parts can then be stitched together using the following
- syntax:-
-
-
- CUT PART2.ZIP PART1.ZIP 64768 0 /A
-
-
- > The completed file PART1.ZIP can then be decompressed in the usual
- manner; PART2.ZIP can be deleted.
-
- For further information you should refer to the FBB SysOp
- documentation section 15.13 on page 97. It is also sometimes
- advisable to discard the last few bytes of the first file section as
- these can often become corrupt during the carrier loss.
-
- It is likely that this operation will become redundant with the
- advent of ZMODEM support in the next general release of FBB.
