- Hello All,
-
- Recently Jeff Randall inquired about the state of XC for Linux.
- I had not posted any changes since last spring. Getting FTP
- access has been difficult. However, Jeff was kind enough to
- post the revisions to XC to sunsite.unc.edu and to tsx-11.mit.edu.
- He has also put together a binary for use with jump tables.
- The fixes and changes are listed below. Those who connect to BBSs
- and DOS based servers should find a considerable improvement in
- the way XC will now handle DOS "ansi" (?) sequences which differ
- from the vt102 standard. Also high ascii characters are translated to
- their latin1 equivalent which makes things easier for non-English
- language use. One of the reasons there was problems compiling the
- current code is that under GCC 1.40 and earlier, stderr wasn't
- buffered. Apparently with the change to GCC 2.x, stderr is now line
- buffered which is why some programs that display characters instead
- of lines don't function properly. I did post a patch to the net last
- summer which fixed this problem but I was unable to get it to an FTP
- SIte.
-
- Here is a summary of the changes:
-
- a) bug fixes,
- b) clean-up of the code,
- c) correction of the buffering problem with stderr (a fault of GCC 2.x),
- d) fixes to the dialing directory to not choke on the DEL character,
- e) improved dos_mode for displaying high-ascii characters and line
- graphics (the latter by mapping them to vt102 graphics sequences),
- f) proper parsing of dos-type "ansi" (?) sequences which differ from the
- vt102 standard.
- g) *selectable* trapping of the DEL character and mapping it to backspace.
-
- It should be noted also that the internal xmodem protocols are consid-
- erably faster and more reliable than in stock XC. CRC or Checksum packet
- verification is automatically negotiated and true 1K Xmodem is implem-
- ented with dynamic on-the-fly switching between 128 byte and 1K packets
- as needed. While rz/sz is usually preffered, there are situations when
- an internal protocol has its advantages. In some situations where there
- are flow control problems, an ACKing protocol such as xmodem will work
- better than a streaming protocol such as zmodem. Of course rs/sz run
- just fine from the XC command line.
