Sean,
A three wire "should" work for PC to TELCOM using some terminal software. A
model 200 has a quirk that requires RTS/CTS to be tied together. I sent that
pinout because it works with simple terminal application sending, it also works
with TPDD clients like LaddieAlpha and it also works with mComm which is a
blend of TPDD and raw TELCOM transfers. I think mComm is the most picky about
the cable being complete since it uses DTR to handle some of the file
transfers. But if you don't have TS-DOS on the machine it may be your easiest
solution to transfer data.
A standard Null modem cable should work but check the pinouts.

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.

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
