       fkmap -l <name>
       fkmap -r                        reset to original mapping
       fkmap -s <file>                 append current to file

This command manages the mechanism ECU uses to recognize function keys
when they are entered at the console.  If supplied, the first argument to
the command must be the recognized name of a function key from the list:

F1 F2 F3 F4 F5 F6 F7 F8 F9 F10 F11 F12 Home End PgUp PgDn CUP CUL CU5 CUR CUD

If only one argument is supplied, the mapping for the specified key is
displayed.  If more than one argument is supplied, the keyboard mapping is
changed.  Arguments 2-n are character code specifiers in the format used
to define a funckeymap entry.

WARNING: If found to be syntactically correct, a mapping change is
installed immediately.  If incorrect mapping of the HOME key is requested,
you may lose control of ECU.

For a description of the other options, see the manual.
#--------------------------------------------------------------------
%hangup
Usage: hangup

This causes DTR to be momentarily interrupted, terminating any
outstanding connection.  Your DCE (modem) must be able to drop carrier
upon loss of DTR.
#--------------------------------------------------------------------
%help
Usage: help [<cmd-name>]

Issuing this command with no argument displays a list of commands
followed by a request for a command for further information.
#--------------------------------------------------------------------
%kbdtest
Usage: kbdtest

This command runs a keyboard test which asks you to press function keys
(e.g., F1).  For each key pressed, ECU gives you the actual character
sequence generated by the key.  It also tells you which function key it
recognizes (if any).  mapping of keyboard generated character sequences
to ECU internal key codes.  The command is useful for verifying and
debugging a "funckeymap" entry.  To exit the test at any time, press the
escape key.
#--------------------------------------------------------------------
%llp
Usage: llp

This command is a shorthand version of 'log /dev/lp'.
/dev/lp must not be under the control of a print spooler.
#--------------------------------------------------------------------
%loff
Usage: loff

This command is shorthand for 'log off'.  If session logging
is active, it is turned off.
#--------------------------------------------------------------------
%log
Usage: log [-s] [-r] [ | off | filename ]
       -s "scratch" previous file contents; otherwise append
       -r "raw" logging; otherwise non-printable characters
          other than tab and newline are omitted from the log

This command controls session logging; issuing the command with no
argument causes the status of session logging to be displayed.  The
special argument 'off' causes active logging to be terminated.  Other
argument values cause logging to start using the argument as a filename.
Issuing a 'log filename' command when logging is already active causes
the previous file to be closed and the new file to be opened.  Switches
are meaningful only when used in conjunction with a filename to start
logging.
#--------------------------------------------------------------------
%memstat
Usage: memstat

Experimental malloc display.  -lmalloc bug may report erroneous data.
#--------------------------------------------------------------------
%nl
Usage: nl

Display the current setting of CR/LF mapping.  For more information,
refer to the 'nlin' and 'nlout' command descriptions.
#--------------------------------------------------------------------
%nlin
Usage: nlin [<y-n>]

This command controls whether or not a newline (NL/LF) character is sent
to the screen upon receipt of a carriage return (CR) from the remote
system.  Most remote computers supply a NL after CR.  When communicating
with another terminal in a "teletype conversation", this is generally
not the case (see also the 'duplex' command).

Issuing the command without <y-n> causes the current setting to be
displayed.  The format of <y-n> is flexible: 'y' or '1' enables
appending NL to CR, 'n' or '0' causes the feature to be disabled.
#--------------------------------------------------------------------
%nlout
Usage: nlout [<y-n>]

This command controls whether or not a newline (NL/LF) character is sent
to the remote system upon transmission of a carriage return (CR) entered
by the keyboard.  Most remote computers do not require (indeed
"dislike") a NL after CR.  When communicating with another terminal in a
"teletype conversation", this is generally not the case (see also the
'duplex' command).

Issuing the command without <y-n> causes the current setting to be
displayed.  The format of <y-n> is flexible: 'y' or '1' enables
appending NL to CR, 'n' or '0' causes the feature to be disabled.
#--------------------------------------------------------------------
%parity
Usage: parity [ None | Even | Odd ]

This command controls the parity of characters transmitted by the
keyboard.  Issuing the command with no parameter displays the current
setting.  When the parameter is supplied, only the first character is
required.  Even or odd parity implies seven data bits; no parity implies
eight data bits.  Parity of incoming characters is not checked.

The setting may be automatically changed as the result of a 'dial'
command.  See also the 'baud' and 'dial' command descriptions.
#--------------------------------------------------------------------
%pid
Usage: pid

This command displays the process id of the ecu transmitter process, the
ecu receiver process and the process ids of ecu's parent and group.
#--------------------------------------------------------------------
%ptrace
Usage: ptrace [ 0 | 1 | on | off]

This command controls whether or not procedure execution is to be
traced.
#--------------------------------------------------------------------
%pwd
Usage: pwd

This command prints the current working directory of the ecu process.
#--------------------------------------------------------------------
%rk
Usage: rk

This command searches the PATH list for 'ckermit' (Columbia University
C-Kermit) and invokes it to receive files.  See the ecu documentation
for modifications necessary to ckermit for ecu operation.  The file
~/.kermrc must be set up to have any desired initialization parameters
you desire.  Refer to C-Kermit documentation for more information.
#--------------------------------------------------------------------
%rs
Usage: rs

This command invokes a SEAlink receive protocol.
#--------------------------------------------------------------------
%redial
Usage: redial [<retry-count> [<pause-interval>]]

This command redials a number previously dialed with the 'dial' command.
Modem status is tested and multiple retries may be made.  <retry-count>
specifies how many retries are to be made.  <pause-interval> specifies
how many seconds the program pauses after a failure to connect.  You
must specify <retry-count> in order to specify <pause-interval>.  The
default value for <retry-count> is 10, for <pause-interval> is 60.

You should know that in some jurisdictions, it is ILLEGAL to dial the
same telephone number more than a specified number of times during some
interval of time.  In any case, specifying <pause-interval> less than 15
seconds is silently changed to 15 seconds.
#--------------------------------------------------------------------
%rev
Usage: rev

This command displays ecu's revision, the transmitter process id and the
date and time ecu was made.
#--------------------------------------------------------------------
%rx
Usage: rx

This command invokes a modified version of Chuck Forsberg's rz program
(version 1.31) to receive files from the remote system using XMODEM/CRC.

After entering the command, you are prompted as to whether or not file
CR/LF characters are to be converted to newlines.  If you are
transferring text files from a system which contain CR/LF line
terminators, you must answer yes to this question.  You should answer no
when transferring binary files, such as executables, .arc files and the
like.  File transfer progress is presented on a visual display.  To
abort the transfer, press your interrupt key (usually DEL unless reset
with stty(C)).
#--------------------------------------------------------------------
%ry
Usage: ry

This command invokes a modified version of Chuck Forsberg's rz program
(version 1.31) to receive files from the remote system using YMODEM
batch with CRC-16 error correction.  The YMODEM is "true YMODEM", not
XMODEM-1k.  File transfer progress is presented on a visual display.  To
abort the transfer, press your interrupt key (usually DEL unless reset
with stty(C)).
#--------------------------------------------------------------------
%rz
Usage: rz

This command invokes a modified version of Chuck Forsberg's rz program
(version 1.44) to receive files from the remote system using
ZMODEM/CRC32.  File transfer progress is presented on a visual display.
To abort the transfer, press your interrupt key (usually DEL unless
reset with stty(C)).
#--------------------------------------------------------------------
%sk
Usage: sk [<file-list>]

This command searches the PATH list for 'ckermit' (Columbia University
C-Kermit) and invokes it to send files.  The file ~/.kermrc must be set
up to have any desired initialization paraeters you desire.  See the ecu
documentation for modifications necessary to ckermit for ecu operation.

After entering the command, you are prompted as to whether or not file
newline characters are to be converted to CR/LF.  If you are
transferring text files to a system which requires CR/LF line
terminators, you must answer yes to this question.  You should answer no
when transferring binary files, such as executables, .arc files and the
like.  You are prompted to enter a list of files to send, which may
contain one or more wildcard specifications.

The file ~/.kermrc must be set up to have any desired initialization
parameters you desire.  Refer to C-Kermit documentation for more
information.
#--------------------------------------------------------------------
%ss
Usage: ss [<file-list>]

This command invokes a SEAlink file transmission protocol.
#--------------------------------------------------------------------
%stat
Usage: stat
