SET File-type Ascii
ASCII files are files of text. The
ASCII character set is an international
standard consisting of 95 printable
characters (including a blank space)
and 33 other 'characters'. You can
create an ASCII file on the Cyber by
using one of the Cyber editors, FSE or
XEDIT, or by giving the TEXT command
when your terminal is in ASCII mode.
.EOR
SET File-type Binary
BINARY files contain information, but
this data is not in the form of text;
it is stored as a sequence of yes-or-no
BITS of data. Kermit reads and writes
BINARY files bit by bit. When writing
a BINARY file, Kermit may add extra
bits to the end of the file to fill out
the last word. If you have a binary
file (not a text file) which you wish
to transfer from one micro to another
via the Cyber, you may want Cyber
Kermit to receive and send it as a
KERMIT file.
.EOR
SET File-type Kermit
A KERMIT file is a special kind of
binary file. You should not use a
KERMIT file to store text. You should
use a KERMIT file only if you do NOT
wish to use your file on the Cyber or
on the Amdahl. The advantage of a
KERMIT file is that Cyber Kermit does
not append data to the file to make it
conform to the Cyber's large wordsize.
KERMIT files make sense only to Cyber
Kermit; they are useless for any other
purpose.
.EOR
SET File-type Display
DISPLAY code files are files of text.
Almost all compilers on the Cyber
accept only DISPLAY code input; if you
are transferring a program text, you
probably need to SET the File-type to
DISPLAY. DISPLAY code files contain
only sixty-four printable characters.
There are no lower-case letters in
DISPLAY code files, so they are some-
times called 'upper-case' files. You
can create a DISPLAY code file on the
Cyber by using one of the Cyber editors
FSE or XEDIT, or by giving the TEXT
command when your terminal is in NORMAL
mode.
.EOR
SET File-type Eight
EIGHT code files are files of text.
Some programs call them ASCII8 or 8
files. You can create an EIGHT code
file on the Cyber with the FSE editor
or with the FCOPY command. Most people
do not need to use this type of file.
.EOR
SET DEBug OFf
Cyber Kermit always writes a record of your Kermit session on
the log file ZZZKLOG. This file ordinarily lists any command
you give except 'SHow' and 'STatus'. Cyber Kermit records in
the log any changes it must make to file names, certain error
messages, and statistics for all file transfers. When DEBug
is SET OFf, the log contains no other information. DEBug is
always OFf unless you SET it ON.
Note: The Cyber command KERMIT can list or print the log file
for you. For information, give the Cyber command
HELPME,KERMIT
.EOR
SET DEBug ON
Cyber Kermit's log file always contains all of your commands
'SHow' and 'STatus', all changes Cyber Kermit makes to file
names, all error messages received from other Kermits, and
statistics for each file transfer. If you SET DEBug ON, your
log file will contain a two-line entry for every packet Cyber
Kermit sends and receives. Ordinarily you should not need to
SET DEBug ON. (If you are curious, use a VERY short file.)
.EOR
SENd
The SENd command tells Cyber Kermit to send a file to another
Kermit. The format of the command is
SENd filename
You must always name the file you wish to SENd.
.EOR
Receive
The Receive command tells Cyber Kermit to receive a file from
another Kermit. This command has two forms:
Receive filename
tells Kermit to receive a file, and that the file should have
the name 'filename' if no local file has that name already.
Receive
tells Kermit to receive a file, and to name the file whatever
the other Kermit calls it, if possible.
.EOR
SERver
The SERver command tells Cyber Kermit that you will no longer
be talking to it directly, but that your commands will arrive
in packets sent by the micro Kermit. To cancel a SERver com-
mand, use the Cyber Escape code. To find out what your Cyber
Escape code is, give the SHow command. (The Cyber Escape
code is CTRL-C unless you have changed it.) You may also
cancel a SERver command by giving the command
FINISH
to your micro Kermit.
.EOR
Exit and Quit
Cyber Kermit (unlike some of its relatives) makes no distinc-
tion between these two commands. Exit and Quit stop Cyber
Kermit so you can give regular NOS commands to Cyber's opera-
ting system (including the GO or BYE command to log out, the
ATTACH and GET commands to make local files -- Cyber Kermit
cannot send permanent files -- or the SAVE, REPLACE, DSAVE,
and DEPLACE commands -- since Cyber Kermit cannot write
permanent files).
.EOR
Push
The Push command allows you to stop Cyber Kermit temporarily
while you to give NOS commands to the Cyber operating system.
Unlike the Exit and Quit commands, the Push command saves all
the options you have SET before giving the Push command; when
you give the next KERMIT command to the Cyber, any values you
set before Pushing will be restored.
.EOR
SET Bit-prefix
To set a different Bit-prefix, use the command
SET Bit-prefix X
where 'X' is the new Bit-prefix. The Bit-prefix must differ
from the Quote-char and the REPeat-char, and it may not be an
upper-case letter or one of the following eight characters:
[ ] / ^ ` #_ ? @
If you do not give an argument, Cyber Kermit assumes you wish
to set the default Bit-prefix '&'.
.EOR
SET Quote-char
To set a different Quote-character, use the command
SET Quote-char X
where 'X' is the character to be used. The Quote-char cannot
be the same as the Bit-prefix or the REPeat-char, and it may
not be an upper-case letter or one of these eight characters:
[ ] / ^ ` #_ ? @
If you do not give an argument, Cyber Kermit assumes you wish
to set the default Quote-char '##'.
.EOR
SET REPeat-char
To set a different REPeat-character, use the command
SET REPeat-char X
where 'X' is the new REPeat-char. The Repeat-char cannot be
the same as the Bit-prefix or the Quote-char, and it may not
be an upper-case letter or one of these eight characters:
[ ] / ^ ` #_ ? @
If you do not give an argument, Cyber Kermit assumes you wish
to set the default REPeat-char '~'.
.EOR
SET DELay
To SET a different DELay period, use the command
SET DELay N
where N is the number of seconds which Cyber Kermit will ask
your micro Kermit to wait for a response. The DELay must be
between 5 and 94 seconds. If you do not give an argument,
Cyber Kermit will set the default DELay period, which is 20
seconds.
.EOR
SET Escape
To SET a different Escape character, use the command
SET Escape X
where X is a letter or one of the following seven characters:
[ ] / ^ ` #_ @
This sets the Escape character to the unprintable character
you produce when you press the CONTROL key together with the
letter or symbol you have selected. The Escape character may
not be the same as the Marker, and it may not be CONTROL with
any one of the letters H, J, M, P, Q, S, T, or X. If you
do not type an argument for this command, Cyber Kermit tries
to SET the default Escape character, CTRL-C.
.EOR
SET Marker
To SET a different Marker character, use the command
SET Marker X
where X is a letter or one of the following seven characters:
[ ] / ^ ` #_ @
This sets the Marker to the unprintable character you produce
when you press the CONTROL key together with the letter or
symbol you have selected. The Marker may not be the same as
the Escape character, and it may not be CONTROL with any one
of the letters H, J, M, P, Q, S, T, or X. If you do not
type an argument for this command, Cyber Kermit tries to SET
Escape to the default character, CTRL-C.
.EOR
SET Packet-length
To SET a different Packet-length for the maximum length of
packet which Cyber Kermit asks to receive, give the command
SET Packet-length N
where N is the length of the longest packet Cyber will then
be able to receive. The Packet-length must be in the range
40 -- 94. The default Packet-length is 94, and if you give
the SET Packet-length command without a parameter, Cyber
Kermit SETs the Packet-length to 94.
.EOR
SET RETry
To SET the maximum number of retries allowed when attempting
to transmit a single packet, give the command
SET RETry N
where N is the maximum number of retries per packet. RETry
must be in the range 3 -- 30. The default RETry limit is 5,
and if you give the SET RETry command without a parameter,
Cyber Kermit SETs the RETry limit to 5.
.EOR
Type
You can give the Type command only if
Cyber Kermit is running as a SERver.
This command is useful for learning
whether you have SET the correct File-
type, because you can interrupt the
Type command from your micro. The
format of the command is
Type Cyberfilename
You are not allowed to Type Binary or
Kermit format files.
.EOR
You can send the following commands to
Cyber Kermit when it is in SERver mode:
SEt-file-type STatus
SHow Type
.EOR
The SEt-file-type command requires one
parameter, the name of a type of file
recognised by Cyber Kermit:
Ascii Eight
Binary Kermit
Display
For more information, consult the Cyber
Kermit User Guide.
