I FTP'd "vcal" from eddie.mit.edu (src/local/vcal/) and attempted to port
it to SCO Xenix. I am having trouble in two areas:
1) the terminal modes are set by a system() call - the BSD version does
a system("stty -cbreak -echo"). Xenix doesn't have cbreak. The closest I
have so far got it to working was to do a "stty -icanon -echo" but this
only updates the screen every fourth character, though it does retain
all the characters typed. However, upon exit, doing "stty sane echoe"
leaves the terminal in screwey mode (no echo, ignore 3 of 4 whitespaces...)
Any thoughts on this one world? Is there maybe a Sys5 version of vcal
around? Is the one from eddie.mit.edu really old or something? Thanks!
2) Upon exit, the program gets an error trying to write (null) file -
is there a directory that doesn't exist under Sys5 that does exist by
default under BSD where calendar files might go?
Thanks for all help!

Try "stty -icanon -echo min '^a' to go into cbreak mode, and "stty icanon echo eof '^d'" to return to normal. The min-eof business is what controls the number of characters read before processing. See termio(7). > Is the one from eddie.mit.edu really old or something? Thanks! Yes, vcal is old. Somewhere there's a rewrite called "month". I never ported it to Xenix, but it looked a little cleaner and had some additional features. Try the comp.sources.unix archives for that one. >2) Upon exit, the program gets an error trying to write (null) file - >is there a directory that doesn't exist under Sys5 that does exist by >default under BSD where calendar files might go? Hmmm... I don't remember that one. Try touching $HOME/.appointments before running vcal. Hope this helps. -- Tom Bertelson Tom.Bertelson@Dayton.NCR.COM ...!ncr-sd!ncrlnk!tbertels

To return to normal, do "stty icanon echo eof='^D' eol='^@'". To see the reason behind these shenanigans: look for "MIN and TIME" on the man page that describes the terminal driver's non-canonical mode. Sorry, I don't know what is causing the other problem.

Try the comp.sources.unix archives for that >one. Even the "month" program in comp.sources.unix archives is (unfortunately) outdated [and I don't see a repost in the near future]. The newest month sources have been rewritten to for portability to compilers with 6-character variable restrictions. It does compile under XENIX (and BSD and SYSV). The known bugs that exist in the comp.sources.unix version have been fixed. In addition to improvements in the code that outputs calendar and appt schedules, one can now check other user's schedules for "meeting" openings and/or conflicts. Any one who wants a copy of the month sources (or the useful "appt" routines) should send mail to me with a valid UUCP return address. -- Marc A. Ries sdcrdcf!---\ ihnp4!------\----- trwrb! --- ries

I don't know much about the System V tty driver, but they overloaded
the EOF char field with something called VMIN & VTIME (or similar, I forget
the exact name), that tell the driver to return after VMIN chars and/or
VTIME time units. Your EOF char is probably ^D which has a value of four.
You can probably get away with setting your EOF char to ^A, which has a value
of one, to get every character. Better solutions probably exist. Have fun!
Thanks for all help!
