I think John has a version of LaddieAlpha for Linux but I'll defer that to him since my information is specific to Windows.

What software would you recommend on the PC side for that? I run Linux.

Sadly it's true that a full null cable that is wired correctly is hard to
find. I keep looking for a source and come up empty. Most places tie the
RTS/CTS lines to ground. There is always the pre-made usb to db25 on ebay.
Since a real serial port on a computer is getting harder to come by this is
a excelent choice.

But I believe the housing is too thick for a model 100 and would require a
25pin gender changer trick to fit. It fits the 102 and the 200 with no
trouble.

I'm sure that Kurt' instructions are the best available, but they
assume that you are going to wire up your own cable, definitely not
for beginners. The serial port on the Model 100 is 25 pins so as well
as a null modem cable you will need a 9 pin to 25 pin adaptor.

I have used the three wire configuration RX, TX,  Gnd,  and have had no
problems (RX/Tx reversed on other end)

Hey, Kurt-

Will a standard null modem work for terminal mode in TELCOM, or do I need
to
go with the pinout below? I see that's the cable used for the PC link…

Sean,

If your using TELCOM, you will need a 9-25 null modem cable. The one
listed
below is a full null cable meaning the RTS/CTS and DTR/DSR pins are not
looped back. Enjoy tinkering.

7 Wire Cable

PC------Model-T
DB9-----DB25
===============
2------>2
3<------3
4<------6
5--GND--7
6<------20
7------>5
8<------4

Thanks, John!

I'm working on a couple of things for follow-up:
Connecting via TELCOM and a null modem cable to various computers (PC,
Mac,
Raspberry Pi) as a terminal, to do file transfer, etc.
Possibly doing some sort of Bluetooth-to-serial hack to connect to
another
system in similar fashion as above.
Doing some dial-up (I need to order or create a modem cable, as the
system I
picked up came with just a printer ribbon cable with no termination)
Spending a day doing my job from the Model 100. (Writing an article from
the
field, filing it, communicating with co-workers via IRC, checking email
via
some sort of gateway?).


If anyone has any tips to share on any of these, I'd appreciate the help
(and will properly credit it). :D
