/*
Originally the entire user interface was in one module, ckuusr.c. Over
the years it has been split into many modules: ckuus2.c, ckuus3.c, ...,
ckuus7.c. ckuus2.c contains the HELP command parser and help-text strings;
ckuusy.c contains the UNIX-style command-line interface; ckuusx.c contains
routines needed by both the command-line interface and the interactive
command parser. ckuusy.c handles command-line arguments.
*/
/*
The ckuus*.c modules depend on the existence of C library features like
fopen, fgets, feof, (f)printf, argv/argc, etc. Other functions that are
likely to vary among different platforms -- like setting terminal modes or
interrupts -- are invoked via calls to functions that are defined in the
platform-dependent modules, ck?[ft]io.c. The command line parser processes
any arguments found on the command line, as passed to main() via argv/argc.
The interactive parser uses the facilities of the cmd package (developed for
this program, but usable by any program). Any command parser may be
substituted for this one. The only requirements for the Kermit command
parser are these:
. Set parameters via global variables like duplex, speed, ttname, etc. See
ckcmai.c for the declarations and descriptions of these variables.
. If a command can be executed without the use of Kermit protocol, then
execute the command directly and set the variable sstate to 0. Examples
include 'set' commands, local directory listings, the 'connect' command.
. If a command requires the Kermit protocol, set the following variables:
sstate string data
'x' (enter server mode) (none)
'r' (send a 'get' command) cmarg, cmarg2
'v' (enter receive mode) cmarg2
'g' (send a generic command) cmarg
's' (send files) nfils, cmarg & cmarg2 OR cmlist
'c' (send a remote host command) cmarg
cmlist is an array of pointers to strings.
cmarg, cmarg2 are pointers to strings.
nfils is an integer.
cmarg can be a filename string (possibly wild), or
a pointer to a prefabricated generic command string, or
a pointer to a host command string.
cmarg2 is an "as-name" - the name to send file(s) under, or
the name under which to store incoming file(s); must not be wild.
A null or empty value means to use the file's own name.
cmlist is a list of filenames, such as passed via argv.
nfils is an integer, interpreted as follows:
-1: filespec (possibly wild) in cmarg, must be expanded internally.
0: send from stdin (standard input).
>0: number of files to send, from cmlist.
The screen() function is used to update the screen during file transfer.
The tlog() function writes to a transaction log.
The debug() function writes to a debugging log.
The intmsg() and chkint() functions provide the user i/o for interrupting
file transfers.
