  15:  The ckuser module contains the terminal input and output functions for Unix
  16:  Kermit.  It includes a simple Unix-style command line parser as well as
  17:  an interactive prompting keyword command parser.  It depends on the existence
  18:  of Unix facilities like fopen, fgets, feof, (f)printf, argv/argc, etc.  Other
  19:  functions that are likely to vary among Unix implementations -- like setting
  20:  terminal modes or interrupts -- are invoked via calls to functions that are
  21:  defined in the system-dependent modules, ck?[ft]io.c.
  22: 
  23:  The command line parser processes any arguments found on the command line,
  24:  as passed to main() via argv/argc.  The interactive parser uses the facilities
  25:  of the cmd package (developed for this program, but usable by any program).
  26: 
  27:  Any command parser may be substituted for this one.  The only requirements
  28:  for the Kermit command parser are these:
  29: 
  30:  1. Set parameters via global variables like duplex, speed, ttname, etc.
  31:     See ckmain.c for the declarations and descriptions of these variables.
  32: 
  33:  2. If a command can be executed without the use of Kermit protocol, then
  34:     execute the command directly and set the variable sstate to 0. Examples
  35:     include 'set' commands, local directory listings, the 'connect' command.
  36: 
  37:  3. If a command requires the Kermit protocol, set the following variables:
  38: 
  39:     sstate                             string data
  40:       'x' (enter server mode)            (none)
  41:       'r' (send a 'get' command)         cmarg, cmarg2
  42:       'v' (enter receive mode)           cmarg2
  43:       'g' (send a generic command)       cmarg
  44:       's' (send files)                   nfils, cmarg & cmarg2 OR cmlist
  45:       'c' (send a remote host command)   cmarg
  46: 
  47:     cmlist is an array of pointers to strings.
  48:     cmarg, cmarg2 are pointers to strings.
  49:     nfils is an integer.
  50: 
  51:     cmarg can be a filename string (possibly wild), or
  52:        a pointer to a prefabricated generic command string, or
  53:        a pointer to a host command string.
  54:     cmarg2 is the name to send a single file under, or
  55:        the name under which to store an incoming file; must not be wild.
  56:     cmlist is a list of nonwild filenames, such as passed via argv.
  57:     nfils is an integer, interpreted as follows:
  58:       -1: argument string is in cmarg, and should be expanded internally.
  59:        0: stdin.
  60:       >0: number of files to send, from cmlist.
  61: 
  62:  The screen() function is used to update the screen during file transfer.
  63:  The tlog() function maintains a transaction log.
  64:  The debug() function maintains a debugging log.
  65:  The intmsg() and chkint() functions provide the user i/o for interrupting
  66:    file transfers.
