Q: How do I connect the 100/200LX to a desktop PC?
A: For the 100LX, HP sells the connectivity pack, (HP F1021A) which
comes with a serial cable, (HP F1015A) a package of various adapters
for different serial connections, (HP F1023A) and software for the
PC.  The PC software includes versions of the 100LX PIM software (but
no Lotus 1-2-3, sorry).  The filer applications let you transfer
files back and forth, and the redirector program lets you use one
machine's disk drive from the other machine (but it's slow).

A similar connectivity pack is available for the 200LX (F1021B,
w/English docs, F1021C with multilingual docs).  The 200LX
connectivity pack includes software to integrate Pocket Quicken with
Quicken for DOS or Windows, in addition to updated versions of the
software in the 100LX connectivity pack.

A "software-only" version of the 200LX connectivity pack is also
available, for those users who already have cables and such from
a 100LX.

Q: What if I don't want to buy the connectivity pack?
A: If you don't want to buy the connectivity pack, you may connect
the palmtop and desktop with a serial cable and use your choice of
DOS connectivity software.  The interlnk/intersvr programs that come
with DOS 6 work fine.  One way to start is to transfer intersvr.exe
to the palmtop using the built-in telecom application on the palmtop
and any terminal emulator on the desktop.  The Kermit file transfer
protocol works well enough.  Then install interlnk on the desktop
according to the documentation, and run intersvr on the palmtop.  Now
you can access the palmtop's drives from the desktop.

200LX users may take advantage of the built-in LapLink Remote
software in the HP's ROM.  A brief sketch of how to do this is:

1. Add the following line to your Palmtop's AUTOEXEC.BAT before
   sysmgr is started.
   Then reboot your palmtop.

2. Copy the following files from D:\BIN on the 200LX to a directory 
   on the PC (use the built-in datacomm application and a terminal 
   emulator, or any other method you choose).

3. Edit the TSI.INI file on your PC as follows:
     In [general], change ComputerName= to something else (eg desktop)
     In [Redirector], change Enabled= to Yes.

4. Edit the LLRA.BAT file on your PC, changing all file paths from 
   D:\BIN to the PC directory you copied them to in step 2.

5. With the PC and palmtop connected via serial cable, enter the
   AppMgr on the palmtop and start the LapLink Remote Access program.

6. On the PC, change to the directory where you copied the LapLink
   files, and type "LLRA".  In a few seconds you should hear beeps
   from both the PC and palmtop indicating that a connection has
   been made.

7. On the PC, type "LLRA /M" to display the drive mapping.

8. To Unload LapLink from the PC, type "LLRA /U".

Q: Where can I get just the HP-100/200LX serial cable without the
Connectivity Kit?
A: EduCALC, etc.  HP sells it as part no. F1015A.  The same cable is
used for HP's calculators (it comes with an adapter to fit their
serial connector), so check the calculator section of a well-equipped
store if you don't see the cable near the HP100/200LX display.

Q: Where do I get an adapter to use HP's serial cable with a modem,
serial printer, Sun workstation, etc.?
A: HP sells a connector/adapter kit (HP F1023A).  The HP serial cable
ends in a female DE9 connection with a null modem, so it's ready to
plug directly into the standard DE9 serial connector found on most
desktop PC's.  The adapter kit contains four adapters, which make
the COMBINATION of HP serial cable + adapter look like:
   0) female DE9 with null modem (stock cable with no adapter)
   1) male DB25 with null modem (for serial printer)
   2) male DB25 without null modem (for modem or other devices)
   3) female DB25 with null modem (for PC with DB25 serial port)
   4) male DE9 without null modem (for modem or anything else you'd
      plug into your desktop's DE9 port).

Try the serial printer adapter to connect to a Sun workstation's DB25
port.  Some other unix workstations are reported to use
MacIntosh-style serial ports, and the MacIntosh serial cable will
work with these.   Similar adapters should be available at any well
equipped computer/electronics store, or you can build your own.  The
adapter kit comes with the connectivity pack.

Q: Where can I get a compatible serial port connector?
A: EduCALC sells a cable with the appropriate connector at one end and
bare wires at the other.  For those who want to make a cable from
scratch a contact and part numbers follow.

Digi-Key Corporation

part# H2004-ND Hirose Electric Co., A3B series 10-pin dual-row, 2mm 
                           connector (HP 100/200LX)
part# H9999-ND Hirose Electric Co., socket terminals, quantity 100
part# H2013-ND Hirose Electric Co., A4B series 4-pin, single-row, 2mm 
                           connector (HP-48, HP-95LX)

If you already have the HP cable, it comes with an adapter to plug the
10-pin connector into a 4-pin HP95 or HP48.  One clever use of this
adapter is use it as a mold to make a "bump" on Digi-Key 10-pin
connector using 5-minute epoxy.  This "bump" is not essential, but it
may help prevent you from inserting the 10-pin connector

Q: How can I connect the 100/200LX to an Apple MacIntosh?
A: HP sells a serial cable to connect the 100/200LX directly to a Mac;
it's part #F1016A.  This handles the physical link, reducing the
problem to "How can I get a Mac to talk to a PC across a serial link?"

DataViz (1-800-733-0030) is a company which makes a product called
MacLink Plus/HP Palmtop, which handles file transfers, and converts
the HP100/200LX application's files (memo, database, phonebook, etc.) to
popular Mac formats (Excel, MacWrite, Word, etc.).  One current
shortcoming is that the "Notes" section of the 100/200LX
Database/Phonebook programs is not supported in the Filemaker
translation.  But this is reportedly being worked on.

MacLink Plus works with all the HP Palmtops (95/100/200).  It
includes the serial cable.  File translations include:

Memo to: MacWrite, MacWrite II, MS Word 4 & 5.x, MS Works, Mac WP
2&3, WriteNow 2, RTF.

Appt book to: Excel 2,3,4, Lotus WKS, MS Works SS 2,3, SYLK, Comma
Separated, Tab Separated, Tab Text

Phone book to: Address Book Plus, Dynodex 2,3, Excel 2,3,4, Filemaker
Pro, Lotus WKS, SYLK, Comma Separated, Tab Separated, Tab Text

Database to: FileMaker Pro, MS Works DB 2,3

Palmtop Lotus to: Excel 2,3,4, Lotus WKS, Ms Works SS 2,3, SYLK,
Comma separateed, Tab Seeparated, Tab Text.

Among other places, it's available directly from DataViz or from
MacWarehouse (1-800-255-6227).

The best answers to generic PC/Mac connectivity are probably found
outside this newsgroup (anyone know where?), but here's a shot at
some alternatives:

Most any terminal program on the 100/200LX (including the built-in
DataComm) will handle simple file transfers via kermit, xmodem, etc.

MacLink Plus/PC is a commercial package made by DataViz which is
intended for use on any IBM-Compatible, and is reported to work on
the 100/200LX, and allow easy file transfer.  But see above for a
customized HP version that supports the HP apps.

Q: How fast is the highest speed for serial port?
A: For a vanilla 100/200LX, the maximum speed for the internal UART
(8250 serial port controller implemented in the 100/200LX) is
19200bps.  With a buffered UART, (NS16550, implemented in many PCMCIA
modems) speeds up to 115200bps work fine.  Note: this does not mean
that 100/200LX can actually send data at 115200bps.  It means that
palmtop can RECEIVE data at 115200bps, without lossage.  For a
100/200LX with double-speed crystal, 38400bps seems to be the maximum
speed with the internal UART.

Your milage may vary depending on the communication software you are
using.  Try using communication software with a very good interrupt
handler implementation.  If you can read Japanese, you may want to try
siam available at:

Also, as described above, do not forget to quit system manager

Q: Intersvr complains about the E: drive when I start it.  What can I
A: This is a stacker/interlink incompatibility.  You could stop using
stacker, but a less drastic solution is to get a copy of SUBST.EXE
from a PC with MS-DOS 5.0 and include the statement 
"SUBST E: A:\somedir" in your AUTOEXEC.BAT.  "somedir" refers to any 
existing directory on your A: drive.
