- MS-DOS Kermit for NEC PC-9801 is one of the "Kermit-MS" family.
- The basic usage is the same as "Kermit-MS" for IBM/PC.
- Therefore, this document describes only the diffrences from the
- IBM/PC.
-
- 1. Terminal emulation options
-
- Summary of the default values:
- Communication port 1 (COM1)
- Terminal emulation VT102
- EscChar ^]
- Display Regular, 8-bit
- Keyinput BIOS
- Keyclick off
- Kanji-code DECcode (see note below)
- Foreground Color White
- Background Color Black
- Highlight Color Yellow
- Modeline Color White
- (Note on Kanji display)
- More precisely, the default character code is assigned as follows;
- GL character set = G0 character set = JIS Roman (almost ASCII)
- G1 character set = DEC special graphics
- G2 character set = JIS Katakana
- GR character set = G3 character set = JIS C6226 (2-byte Kanji).
- Therefore, a SO invokes DEC special graphics and sending the JIS
- X 0208 code with 8th bit on (DEC Kanji code) results the the Kanji
- displayed.
- These assignments can be changed by sending the
- 'invoke' or 'designate' escape sequence from the host. In this
- case, DEC-Kanji may not be displayed.
-
- The following options are diffrent from IBM/PC
-
- SET BAUD baud-rate
- The useful baud rates supported range from 300 to 9600 for CPU
- clock 8MHz, and from 300 to 19200 for 10MHz clock.
-
- SET PORT {number, COMn, Device [devicename], UB-NETCI}
- The available ports are 1, 2, 3, or their equivalents COM1, COM2,
- COM3. However, current program only works on COM1.
-
- In the case of device, the communication port is controlled by
- MS-DOS device-driver. The default device name is AUX. The
- device-driver for AUX is RSDRV.SYS. The CONFIG.SYS must
- include
-
- DEVICE = RSDRV.SYS
-
- To set-up the AUX device, you must invoke the SPEED command
- before using this device. For example,
-
- SPEED RS232C-0 1200 BITS-8 PARITY-NONE STOP-1 XON
-
- ( or SPEED R0 B8 PN S1 XON ).
-
- If Ungermann-Bass PC-NIU N98 board is installed, UB-NETCI port
- is also available. Note that the port name and the usage is
- diffrent from IBM/PC. See section 2 for more details.
-
- SET TERMINAL {VT102, TEK4014, NONE}
- Kermit-MS for NEC PC-9801 emulates two types of terminals,
- DEC VT102 and Tektronix 4014. Heath/Zenith-19 and VT52 are not
- supported.
-
- The set-up related SET TERMINAL commands:
-
- CHARACTER-SET {UK, US}
- Not implemented. See KANJI-CODE command for Japanese character sets.
-
- COLOR
- See FOREGROUND.
-
- COOKED-LOG {ON, OFF}
- If it is ON, logging is made just before putting the character
- on the screen. All control characters are eliminated except for
- CR, LF, HT(TAB), VT . (i.e., Kanji code is converted to Shift-JIS).
- All ESC sequences are eliminated.
-
- CURSOR-STYLE
- Not implemented.
-
- FOREGROUND {WHITE, YELLOW, CYAN, GREEN, RED, BLUE, MAGENTA, BLACK}
- Specify color for normal attribute characters. This color is used
- in VT102 and TEK4014 emulation modes and not affected to the dumb
- terminal screen.
-
- HIGHLIGHT {WHITE, YELLOW, CYAN, GREEN, RED, BLUE, MAGENTA, BLACK}
- The bold characters are displayed in diffrent color in VT102
- emulation mode. This command specifyes the color for bold
- characters.
-
- KANJI-CODE {DEC-code, Shift-JIS, JIS-7, NONE}
- Set the Kanji-Kana code to be used in connect mode. The Kanji-
- Kana characters from keyboard are translated to the specified code
- before sending to the communication port and characters received
- from communication port are translated from specified code to the
- NEC-PC9801 internal Kanji-Kana code before displaying or printing.
-
- KEYINPUT {BIOS, CON}
- Specifies keyinput mode. In BIOS mode, keyboard is read via
- NEC-PC9801 bios. In this mode, almost all the keys have their
- own scan codes. However, Japanese front end processors except for
- ATOK6 are not compatible with this mode.
- To adapt many kind of Japanese front end processors, keyinput via
- standard MS-DOS console (CON) i/o is also available. The function
- keys, arrow keys etc., are programmed to return the same scan-code
- as in DIRECT mode.
- See section 2 for keymap.
-
- MODELINE-COLOR {WHITE, YELLOW, CYAN, GREEN, RED, BLUE, MAGENTA, BLACK}
- Specify color for mode line.
-
- GRAPHICS
- Not necessary. The graphic VRAM of the NEC-PC9801 has 640x400
- pixels.
-
- MARGIN-BELL
- Not implemented.
-
-
- ROLL
- Not implemented.
-
- SCREEN-BACKGROUND
- See BACKGROUND.
-
- TAB
- Not implemented. Tabs are set at every 8th column and can be
- changed only by host commands.
-
-
- 2. Keyboard mapping
-
- Unfortunately, many of the Japanese front end processors are not compatible
- with NEC keyboard bios. Therefore, this program has two modes for keyboard
- inputs, direct mode (read via bios) and CON mode (read using standard MS-DOS
- console i/o). The latter is compatible with all the Japanese front end
- processors. Special keys are programmed to return the same code as
- in direct mode. However, the keypad keys except for HOME-CLR and HELP are not
- programable, so that keypad keys cannot be distinguished from normal alpah-
- numeric keys in a standard way.
-
- The following table shows the diffrences of the scan codes between two modes.
-

- 3. Network interface
-
- In this program, only supported network interface is Ungermann-Bass
- PC-NIU N98. This interface board is programable, and Ungermann-Bass supplies
- two kinds of network protocol software, XNS (Net/One) and TCP/IP. User must
- load the appropriate program before using this interface.
-
- 3.1 XNS (Net/One)
-
- The loading procedure to use this protocol is
-
- A> NET START urdr <local computer name>
-
- Then start Kermit,
- A> KERMIT
-
- Kermit-MS> SET PORT UB-NETCI
- Kermit-MS> connect
-
- Then you get the prompt
-
- You may now enter Net/One commands
- >>
-
- 3.2 TCP/IP
-
- Before using this protocol, you must load the protocol program by typing
-
- A> etws
-
- The Kermit-MS works under the 'tn' program which is supplied by Ungermann-
- Bass. The procedure is
-
- A> tn -e Kermit
-
- Kermit-MS> SET PORT UB-NETCI
- Kermit-MS> connect
-
- Then you get the prompt
-
- TELNET>
-
- Because that the 'telnet' is the terminal emulation porgram, there are a few
- problems for file transfer. As a default, 'telnet' has escape sequences to
- hold or disconnect session without logout procedure. This means that the
- 'telnet' always checks incoming characters and causes sending file to be
- extreamly slow. (On the other hand, receiving file is fast because of no
- checking for receiving characters.) It is possible to set the 'telnet' in
- transparent mode,
-
- TELNET> set binary on .
-
- After setting this mode, the speed of the send-file is almost the same as
- that of the receive-file.
- However, this is very dangerous. After that, you cannot control the session
- from the PC side.
-
- For these reasons, it is strongly recomended to use the FTP program for
- file transfer.
-
-
- 4. Kana-Kanji display
-
- Kana-Kanji is the Japanese character set. The characters are mapped to
- 2-byte codes. Officially, these codes and the procedure to interchange
- the codes are defined in the following Japanese Industrial Standards (JIS);
-
- JIS X 0208:
- Code of the Japanese Graphic Character Set
- for Information Intercahnge
-
- JIS X 0202:
- Code Extension Techniques for Use with the Code
- for Information Interchange .
-
-
- Unfortunatly, these standards are NOT widly used. Many computers use their
- original procedures to handle X 0208 character set not only for internal code
- but also for comunications. MS-DOS machine uses so called 'Shift-JIS' code
- (the name is not appropriate because Shift-JIS is not JIS). Therefore, this
- program has Kanji-code parameter as terminal set-up parameters.
-
- 4-1.JIS and DEC Kanji
-
- This VT102 is programmed as a JIS Kanji terminal. This terminal has the
- following graphic sets:
- o JIS roman graphics
- o JIS katakana graphics
- o JIS X 0208 2-byte Kanji graphics
- o DEC special graphic
- In general, to display the code in some graphic set, you must "designate"
- the graphic set as one of G0, G1, G2 or G3. Then you must "invoke" one of
- the G0 through G3 into GL or GR. To display the GR character set,
- you must send the code with 8th bit on.
- As a default setting, the character sets are assigned as follows;
-
- GL <- G0 <- JIS roman (X 0201)
- G1 <- DEC special graphics
- G2 <- JIS katakana (X 0201)
- GR <- G3 <- JIS kanji (X 0208) .
-
- A SO code (0/14) invokes G1 character set to GL. Therefore, after receiving
- SO code, terminal displayes DEC special graphics for D0 characters (2/0 -
- 7/E) in this case. The 2-byte Kanji-code can be displayed by sending the
- JIS X 0208 code with 8th bit on (i.e., DEC Kanji code) because it is assigned
- to GR character set.
-
- 4-2. Invocation and designation of the graphic set
-
- The following escape sequences and C0 characters can be used to invoke
- or to designate the graphic set:
-
- To designate the single byte graphic set:
- ESC 02/08 F or ESC 02/12 F designates the graphic set to G0
- ESC 02/09 F or ESC 02/13 F designates the graphic set to G1
- ESC 02/10 F or ESC 02/14 F designates the graphic set to G2
- ESC 02/11 F or ESC 02/15 F designates the graphic set to G3
-
- where
- F is 04/10 for JIS roman
- 03/00 for DEC special graphics
- 04/09 for JIS katakana
- any other code in the range 03/00 to 07/14 designates the JIS roman
- graphics.
-
- To designate the multi-byte graphic set:
- ESC 02/04 02/12 F or ESC 02/04 F designates to G0
- ESC 02/04 02/13 F or ESC 02/04 02/09 F designates to G1
- ESC 02/04 02/14 F or ESC 02/04 02/10 F designates to G2
- ESC 02/04 02/15 F or ESC 02/04 02/11 F designates to G3
-
- where
- F is 04/02 for JIS kanji (X 0208)
- any other code in the range 03/00 to 07/14 designates the JIS X 0208
-
- To invoke the graphic set:
- SI (00/15) invokes the G0 to GL
- SO (00/14) invokes the G1 to GL
- ESC 07/14 invokes the G1 to GR
- ESC 06/14 invokes the G2 to GL
- ESC 07/13 invokes the G2 to GR
- ESC 06/15 invokes the G3 to GL
- ESC 07/12 invokes the G3 to GR
-
- Therefore, the default setting is equivalent to the following escape sequences;
-
- ESC 02/08 04/10
- ESC 02/09 03/00
- ESC 02/10 04/09
- ESC 02/04 02/15 04/02
- SI
- ESC 07/12
-
- 4-3. Shift-JIS
-
- Shift-JIS is not an industrial standard, but widly used on many Japanese
- MS-DOS machines.
-
-
- 5. Sending Kana-Kanji codes
-
- This program is designed to be able to send Kana-Kanji characters in the
- following codes;
-
- - DEC code (almost equivalent to Extended Unix Code)
- - JIS code in 7-bit environment
- - Shift-JIS code.
-
- To select the code system,
-
- Kermit-MS>set terminal kanji-code <code specification>
-
