#--------------------------------------------------------------------
%ax
Usage: ax [<param>]

<param> may be a single ASCII character, a standard ASCII identifier
(such as ETX), or a two-character control character identifier (such as
^C, typed as a caret followed by a C).

If no parameter is supplied, a table of control characters is printed
containing decimal, octal, hex, ASCII identifiers and two-character
control character identifier.
#--------------------------------------------------------------------
%xa
Usage: xa [<hex-val>]

<hex-val> is a hexadecimal value between 0 and FF; the parity (sign) bit
is stripped and the equivalent ASCII character value is displayed.

If no parameter is supplied, a table of control characters is printed
containing decimal, octal, hex, ASCII identifiers and two-character
control character identifier.
#--------------------------------------------------------------------
%oa
Usage: oa [<octal-val>]

<octal-val> is a octal value between 0 and 0377; the parity (sign) bit
is stripped and the equivalent ASCII character value is displayed.

If no parameter is supplied, a table of control characters is printed
containing decimal, octal, hex, ASCII identifiers and two-character
control character identifier.
#--------------------------------------------------------------------
%da
Usage: da [<decimal-val>]

<decimal-val> is a decimal value between 0 and 0377; the parity (sign)
bit is stripped and the equivalent ASCII character value is displayed.

If no parameter is supplied, a table of control characters is printed
containing decimal, octal, hex, ASCII identifiers and two-character
control character identifier.
#--------------------------------------------------------------------
%autorz
Usage: autorz [off | on | ]

ECU in the interactive mode (no procedure executing) can interpret a
SUB, 'B', '0', '0' receive data sequence as a ZMODEM ZRQINIT frame and
automatically begin a ZMODEM receive operation.  This command controls
or displays this feature.  By default, this feature is turned on.
#--------------------------------------------------------------------
%baud
Usage: baud [<baud-rate>]

<baud-rate>, if specified, must be taken from the values 110, 300, 600,
1200, 2400, 4800, 9600, 19200 and 38400.  On some systems, 19200 and
38400 may not be supported.  If a baud rate less than 300 is selected, 2
stop bits are automatically specified; other baud rates set 1 stop bit.
If <baud-rate> is not supplied, the current baud rate is displayed.

The setting may be automatically changed as the result of a 'dial'
command.  See also the 'dial' and 'parity' command descriptions.
#--------------------------------------------------------------------
%bn
Usage: bn [ off | on | alert ]
       bn [ 0 | 1 | 2 ]

"bell notify": If no parameter is supplied, the current setting is
displayed.  Specifying 0 or off disables the facility; 1 or on causes
an audible alarm to be sounded upon receipt of a bell (0x07)
character from the remote system; 2 or alert causes an audible alarm
upon receipt of ANY characters.  This command may not be functional
in the version for your system.
#--------------------------------------------------------------------
%break
Usage: break

This command sends a break signal to the remote system.
#--------------------------------------------------------------------
%cd
Usage: cd [<dir-path>]

This command allows you to change the working directory of the ecu
process.  If <dir-path> is supplied, the previous working directory is
displayed, and <dir-path> is made the new working directory.  A history
of previous directory changes is maintained.  Entering the 'cd' command
shows the numbered history list and allows you to select a new directory
by entering the number.  Other commands allow deletion of directories
from the list or saving the list to file ~/.ecu/dir.  This file is
automatically read at ecu startup, providing a convenient list of
directories available for quick selection.
#--------------------------------------------------------------------
%conxon
Usage: conxon [<arg>]
where <arg> is on    honor ^S/^Q local flow control (DEFAULT)
               off   pass ^S/^Q to remote

This command enables or disables console xon/xoff flow control.
If the argument is omitted, the current flow control state is
displayed.  If on, typing ^S/^Q stops or restarts the local
console driver output.  If off, ^S and ^Q are passed to the
remote (for EMACS, of course -- who else?).
#--------------------------------------------------------------------
%dcdwatch
Usage: dcdwatch [<dcdwatch-param>]

This command controls the DCD watcher.  The optional parameter may be:
   y  yes - enable DCD watcher
   n  no - disable DCD watcher
   t  terminate - terminate ECU on loss of DCD
Entering the command without an argument shows the current status.

The DCD watcher when enabled causes ECU to monitor the DCD line (within
the limits imposed by the OS with its CLOCAL=0 functionality).  When the
watcher is on and DCD drops, ecu automatically performs the action of
the interactive or procedure hangup command.  If the 't'erminate option
is chosen, then after hangup processing is complete, the ECU program
will terminate.

The state of the watcher may be changed by the use of the dial command
which uses a directory entry that changes the DCD watcher status.  See
the manual sections on the interactive commands 'dcdwatch' and 'dial'.
#--------------------------------------------------------------------
%dial
Usage: dial [<dial-param>]

<dial-param> may take one of two forms, a telephone number to dial or a
logical name which can be found in the user phone directory (in file
~/.ecu/phone).

If a telephone number is supplied, the phone number is dialed; you must
first have set the desired baud rate and parity using the 'baud' and
'parity' commands.  If a logical name is entered, the phone directory is
searched; if the entry is found, the baud rate and parity is
automatically set and the number dialed.

If <dial-param> is not supplied, then a screen-oriented self-documenting
directory manager is executed; you may scan the the directory to select
a number to dial, as well as add, remove and edit entries.  See also
'baud' and 'parity'.
#--------------------------------------------------------------------
%do
Usage: do <procname> [<arg> ... ]

Perform ecu procedure.  Ecu searches for <procname>.ep in the current
directory.  If the file is not found, the program looks for the file in
the ~/.ecu directory.  One or more arguments may be passed to the
procedure.
#--------------------------------------------------------------------
%duplex
Usage: duplex [ Full | Half ]

This command specifies whether or not ecu is to locally echo characters
typed by you at the keyboard.  The overwhelming majority of remote
systems provide the echo function, in which case full duplex must be
used.  For the rare occasions when the remote system does not echo your
keyboard input, setting half duplex will allow you to see what you are
typing.

When communicating with another terminal in a "teletype conver- sation",
setting half duplex is generally required.  In such cases, use of the
'nl', 'nlin' and 'nlout' commands may also be required.

The default setting for duplex is full.
#--------------------------------------------------------------------
#%esc
#Usage esc <hex-constant>
#"command escape ": This command is used only on non-XENIX systems.
#It specifies the equivalent character for the HOME key used
#by XENIX versions of ecu to enter the commands being described
#by this help function.  The default setting for this command escape
#s '%'.  To change the value, you must enter the hexadecimal value
#of the desired character; it must be in the range 01 through 7F.
#You may use the 'ax' command to aid in converting an ASCII
#character to the appropriate hexadecimal value.
#--------------------------------------------------------------------
%fasi
Usage: fasi [reset]

This command displays or resets the FAS/i tty driver statistics.
The command is found only in versions compiled for FAS/i support.
#--------------------------------------------------------------------
%fi
Usage: fi [<filename>]

"file insert": This command causes file characters to be inserted into
the transmit data stream as though they had been entered at the
keyboard.  If <filename> is not entered on the command line, a prompt
for the filename is made.  Once the filename has been entered and file
has been opened, you are asked whether the file should be transmitted at
full speed, by "echo pacing" or by a single line at a time.  You may
also append an 'f', 'e' or 's' argument to the command line.  If your
remote can tolerate it, full speed transmission is the fastest.
Pressing the interrupt key (DEL) stops a full speed transmission.  By
specifying echo pacing, it is possible to increase the likelihood of
proper receipt.  Pressing the interrupt key (DEL) stops an echo paced
transmission.  As a last resort, if echo pacing is not working for you,
(i.e., you are using the command in an environment where the remote does
not echo your characters), use single line at a time transmission.  You
must press the space key to initiate sending each line.  Pressing 'ESC'
or 's' stops the transfer.
#--------------------------------------------------------------------
%fkey
Usage: fkey [<keyset_name>]

This command allows the mapping of function keys F1-F12, PgUp, PgDn, End
and Ins and the cursor up, down, left and right keys to emit a desired
sequence of characters when a function key is pressed.  <keyset_name>
specifies which key set in ~/.ecu/keys is to be selected: Sample entry
in ~/.ecu/keys:

hayes
	F1:escape:+ + +
	F2:autoans:A T S 0 = 1 cr
	F3:dial:A T D T
bbs
	F1:cancel:^K
	F2:yes:y cr

If a keyset_name matches a logical dial directory name, it is loaded
when the number is dialed.
#--------------------------------------------------------------------
%fkmap
Usage: fkmap                           display current mapping
       fkmap <keyname>                 display single key mapping
       fkmap <keyname> <keylist>       modify a key's mapping
