-
-
- OVERVIEW
- --------
-
- Kermit file-transfer protocol enables you to transfer files between your HP 48
- calculator and a computer. Kermit is built into the HP 48, and when you also
- have Kermit running on your computer, your HP 48 and computer are ready
- to "talk to each other."
-
- Kermit protocol was developed at the Columbia University Center for
- Computing Activities. Kermit is available for many systems for a nominal
- fee from Columbia and from various user group organizations.
-
-
- PROCEDURE
- ---------
-
- You may need to refer to your calculator and computer manuals to help you
- follow this procedure.
-
- 1. Connect the 4-pin end of the serial interface cable to your HP 48;
- connect the 9-pin end of the cable to the COM1 or COM2 port on your
- computer. (This may require the 25-pin adapter.)
-
- 2. Run Kermit on the computer. (From the prompt for the directory in
- which Kermit was installed, type KERMIT and press [ENTER].)
-
- 3. Configure the Kermit port setting to match the port to which the
- serial cable was connected in step 1, and configure the Kermit baud
- setting to match the computer's setting. (You can use the Kermit SET
- command to do both of these--see the "EXAMPLE" section below.)
-
- -------------------------------------------------------------------------------
- NOTE: The default baud for the HP 48 is 9600. So, unless you need
- to use another setting for your system, you should set your computer
- and Kermit to 9600 baud also.
- -------------------------------------------------------------------------------
-
- 4. Make sure the HP 48 baud matches the setting from step 3. Also, make
- sure the IR/wire transmission mode is set to "wire." (Both of these
- parameters can be viewed and set using the I/O SETUP menu on the HP 48.)
-
- 5. Follow the instructions in the "HP 48 Owner's Manual" for transferring
- data between an HP 48 and a computer.
-
- 6. When you're finished, type Q and press [ENTER] to quit Kermit.
-
-
- KERMIT HELP
- -----------
-
- To get help in Kermit on the computer, type a question mark (?) and press
- [ENTER]. Kermit displays a list of commands. To get help on a specific
- command, type the name of the command followed by a space and then a question
- mark, and then press [ENTER]. For example, type SET ? and press [ENTER] to
- get help on the SET command.
-
-
- EXAMPLE
- -------
-
- This example assumes that you've connected the serial cable both to your
- calculator and to the COM1 port in the computer and that you have a
- variable in your HP 48 VAR menu named DATA1. It also assumes that the HP 48
- baud and the computer baud are set to 9600 and that you've prepared for a file
- transfer as described in the "HP 48 Owner's Manual."
-
- Here are the keystrokes to transfer the file DATA1 from the HP 48 to the
- computer:
-
- Computer Keystrokes: KERMIT [ENTER] Runs Kermit protocol.
-
- SET PORT 1 Sets Kermit port to COM1.
-
- SET BAUD 9600 Sets Kermit baud to 9600 to
- match the calculator and the
- computer.
-
- RECEIVE [ENTER] Prepares the computer
- to receive a file.
-
-
- Calculator Keystrokes: [VAR] ['] {DATA1} Recalls the variable to be
- transferred to the stack.
-
- [left-shift][I/O] Selects the I/O menu and
- {SEND} transfers the file to the
- computer. The file DATA1 is
- copied into the directory in
- which Kermit resides.
-
-
- Now assume that you quit Kermit and edited the file DATA1 on your computer.
- Here are the keystrokes to send it back to the HP 48:
-
-
- Computer Keystrokes: KERMIT [ENTER] Runs Kermit protocol.
-
- SET PORT 1
-
- SET BAUD 9600
-
- SEND DATA1 [ENTER] Transfers the edited DATA1
- to the HP 48, where it shows
- up in the VAR menu. (If the
- old DATA1 still exists, the
- new DATA1 is given an
- extension so the old version
- isn't overwritten.)
-
-
- Calculator Keystrokes: [left-shift][I/O] Prepares the HP 48 to receive
- {RECV} a file.
-
- HELPFUL HINTS
- -------------
-
- o The Kermit PUSH command gets you out of Kermit temporarily and into DOS
- so that you can manipulate files. You return to Kermit by typing EXIT
- and pressing [ENTER].
-
- o The Kermit STATUS command displays a screen showing the current Kermit
- configuration settings. The baud and port settings are the first two
- in the list.
-
- o You can execute the DOS directory command from within Kermit by typing
- DIR and pressing [ENTER].
-
- o For additional information on Kermit protocol, a book by Frank da Cruz,
- "KERMIT, A File Transfer Protocol" (1987. Bedford, MA: Digital Press) is
- available in many bookstores or can be ordered.
