after the book was printed.  Also SET TELNET BUG BINARY-U-MEANS-ME-TOO.
The default for both is OFF.  ON should be used when communicating with a
Telnet partner (client or server) that mistakenly believes that telling
C-Kermit to enter Telnet binary mode also means that it, too, is in binary
mode, contrary to the Telnet specification, which says that binary mode must
be negotiated in each direction separately.

The RLOGIN section on page 123 does not make it clear that you can use the
SET TELNET TERMINAL-TYPE command to govern the terminal type that is reported
by C-Kermit to the RLOGIN server.

Note that the SET TCP commands described on pages 122-123 might be absent;
some platforms that support TCP/IP do not support these particular controls.

2.3. The EIGHTBIT command

EIGHTBIT is simply a shorthand for: SET PARITY NONE, SET TERMINAL BYTESIZE 8,
SET COMMAND BYTESIZE 8; that is, a way to set up an 8-bit clean connection
in a single command.

2.4. The Services Directory

Chapter 7 of "Using C-Kermit" does not mention the ULOGIN macro, which is
used by our sample services directory, CKERMIT.KND.  Unlike UNIXLOGIN,
VMSLOGIN, etc, this one is for use with systems that require a user ID but
no password.  Therefore it doesn't prompt for a password or wait for a
password prompt from the remote service.

(7) SCRIPT PROGRAMMING

7.1. INPUT Command Details

The description of the INPUT command on page 422 fails to mention the
following two points about the timeout:

 1. "INPUT -1 text" (or "INPUT \%x text", where \%x is any variable whose 
    value is -1 or less) means "wait forever".

 2. "INPUT 0 text" means don't wait at all -- fail immediately if the text 
    is not already waiting to be read.

The same points apply to MINPUT.

(8) USING OTHER FILE TRANSFER PROTOCOLS

(9) NEW COMMAND-LINE OPTIONS

III. APPENDICES

Figure II-5 on page 494.  The pin assignments of the Mini Din-8 connector
are not described anywhere.  As noted in the text, these tend to vary from
vendor to vendor.  One common arrangement is:

  1. HSKout (Handshake out -- definition depends on software)
  2. HSKin  (Handshake in or external clock)
  3. TxD-
  4. Not used
  5. RxD-
  6. TxD+
  7. Not used
  8. RxD+

Note the "balanced pairs" for Receive Data (RxD) and Transmit Data (TxD), and
the utter lack of modem signals.  These connectors follow the RS-423 standard,
rather than RS-232.  In some arrangements, Pin 1 is used for DTR and Pin 2 for
CD; in others Pin 1 is RTS and Pin 2 is CTS.

IV. ERRATA & CORRIGENDA

The following errors in "Using C-Kermit", Second Edition, first printing,
have been noted:

First, some missing acknowledgements: JE Jones of Microware for help with
OS-9, Nigel Roles for his help with Plan 9, Lucas Hart for help with VMS and
Digital UNIX, Igor Kovalenko for his help with QNX.

PAGE    REMARKS
COVER   "COS" is a misprint.  There is no COS.  Pretend it says "SCO" or "VOS".
123     Third paragraph from bottom: "..otherwise if a your local username.."
        should be "..otherwise your local username..".
298     Table 16-2, Portuguese entry.  Column 4/00 should show section sign,
        not acute accent.
453     "the the" (last paragraph) should be "the".
454     EOT (last paragraph) is End of Transmission, not End of Text.
457     "macro for and" (last paragraph) should be "macro and".
560-563 HP-Roman8 missing from Table VII-4.  It is listed in section II(6).
565     "d stroke" in Table VII-5 has the wrong appearance; the stem should
        be upright.  The letter shown in the table is actually a lowercase
        Icelandic eth, which has a curved stem.
601-604 BeBox, BeOS, Plan 9, and probably others not listed in trademarks.
604     The words "SCRIBE TEXT FORMATTER" appear at the end of the last
        sentence of the first parapgraph of the Colophon.  They should have
        been in the Index.

Please send reports of other errors to the authors, as well as suggestions for
improvements, additional index entries, and any other comments.
