Unix flavors of Omen Technology's Professional-	  YAM communications software are available for	dial-out	  applications.	 Unix Professional-YAM supports	dial-out	  applications with telephone directory, a powerful script	  language with	learn function,	high quality multiple protocol	  support, and UUCP port arbitration.	  SSSSzzzz sends one or more files with ZMODEM protocol.	  ZMODEM greatly simplifies file transfers compared to XMODEM.	  In addition to a friendly user interface, ZMODEM provides	  Personal Computer and	other users an efficient, accurate,	  and robust file transfer method.	  ZMODEM provides complete EEEENNNNDDDD----TTTTOOOO----EEEENNNNDDDD data integrity between	  application programs.	 ZMODEM's 32 bit CRC catches errors	  that sneak into even the most	advanced networks.	  Advanced file	management features include AutoDownload	  (Automatic file Download initiated without user	  intervention), Display of individual and total file lengths	  and transmission time	estimates, Crash Recovery, selective	  file transfers, and preservation of exact file date and	  length.	  The ----yyyy option	instructs the receiver to open the file	for	  writing unconditionally.  The	----aaaa option causes the receiver	  to convert Unix newlines to PC-DOS carriage returns and	  linefeeds.	  SSSSbbbb sends one or more files with YMODEM or ZMODEM protocol.	  The initial ZMODEM initialization is not sent.  When	  requested by the receiver, ssssbbbb	supports YYYYMMMMOOOODDDDEEEEMMMM----gggg with	  "cbreak" tty mode, XON/XOFF flow control, and	interrupt	  character set	to CAN (^X).  YYYYMMMMOOOODDDDEEEEMMMM----gggg (Professional-YAM gggg	  option) increases YMODEM throughput over error free channels	  (direct connection, X.PC, etc.) by disabling error recovery.	  On Unix systems, additional information about	the file is	  transmitted.	If the receiving program uses this	  information, the transmitted file length controls the	exact	  number of bytes written to the output	dataset	and the	modify	  time are set accordingly.	  SSSSxxxx sends a single _f_i_l_e with XXXXMMMMOOOODDDDEEEEMMMM or	XXXXMMMMOOOODDDDEEEEMMMM----1111kkkk protocol	  (sometimes incorrectly called	"ymodem").

Restricted mode	restricts	  pathnames to the current directory and PUBDIR	(usually	  /usr/spool/uucppublic) and/or	subdirectories thereof.	  The fourth form sends	a single COMMAND to a ZMODEM receiver	  for execution.  ZZZZccccoooommmmmmmmaaaannnndddd exits with the COMMAND return	  value.  If COMMAND includes spaces or	characters special to	  the shell, it	must be	quoted.	  The fifth form sends a single	COMMAND	to a ZMODEM receiver	  for execution.  ZZZZccccoooommmmmmmmaaaannnnddddiiii exits as soon as the receiver has	  correctly received the command, before it is executed.	  The sixth form (sz -T) outputs all 256 code combinations to	  the terminal.	 The hex value of the character, a space, and	  the raw character are	sent, 8	per line.  In you are having	  difficulty sending files, this command lets you see which	  character codes are being eaten by the operating system or	  network.  The	terminal program must be set to	display	all	  256 codes in a distinct form.	 Check that each code is sent,	  and that the 8th bit on codes	0x80 to	0xFF is	set.	  Sz -T	then allows the	caller to input	characters which are	  echoed in hex.  You should check that	all control characters	  can be input this way.	  The meanings of the available	options	are:	  ++++    Instruct	the receiver to	append transmitted data	to an	       existing	file (ZMODEM only).	  aaaa    Instruct	the ZMODEM receiver to convert text file	       format as appropriate for the receiving system.	Valid	       only for	ZMODEM.	  bbbb    (ZMODEM)	Binary override: transfer file without any	       translation.	  cccc    Instruct	the receiver to	change the pathname if the	       destination file	exists.	  dddd    Change all instances of "." to "/" in the transmitted	       pathname.  Thus,	C.omenB0000 (which is unacceptable to	       MSDOS or	CP/M) is transmitted as	C/omenB0000.  If the	       resultant filename has more than	8 characters in	the	       stem, a "." is inserted to allow	a total	of eleven.	  eeee    Escape all control characters and the all ones	       character (0xFF); normally only XON, XOFF, and Ctrl-X	       are escaped.	  ffff    Send Full pathname.
