TELCOM has no file transfer ability. All it can do is capture text from 
the serial port to a file and it can read a file and send it out the 
serial port.


That is missing too many things. No binary data, no machine language 
programs, not even 8-bit text, no error detection, let alone error 
correction, it can't even tell when a file begins or ends out of any 
other data coming in the serial port, nor can tell the host side when 
sending a file.


You have to do all those kinds of things yourself with separate programs 
in a dozen laborious, inefficient, error-prone steps before and after 
the actual transfer, to manage to get a file transferred that way. 
(encode the file with some kind of utility, generate a checksum of 
either the original file or maybe the encoded file, start the capture on 
one end, start sending from the other end, somehow arrange to ensure 
that there is not a single byte of other junk included in the capture 
before or after the file contents, run a decoder program on the 
receiving end to unpack the encoded file back into it's real form, run a 
checksum program to verify that, delete the encoded version, have an 
empty machine so that the ram can all be used up on having both the file 
you want and the 2x size encoded copy of it and the decoder app all in 
ram at the same time (so no big files), and then how did you get the 
encoder or decoder app onto the 100 in the first place? Manually type it 
in? Cassette? TELCOM capture an ascii format BASIC program and just hope 
it wasn't corrupted?


You only do that once per reset simply because the system rom provides 
no other option besides the cassette interface (for instance TELCOM has 
no xmodem), and you physically have no choice. So you do that once, just 
to bootstrap some kind of software to do that job for real the rest of 
the time, until the next time you wipe the machine.


So if I can upload and download files, why can't I build my own FTP 
SERVER? or whatever server, put the program files on it and download 
them to the Model100?


I'm not sure what exactly is the question. Yes you can place files on a 
computer and download them to the 100. That's exactly all a TPDD 
emulator (akak tpdd server) does is exactly that.


It's not FTP though. FTP is a tcp/ip protocol. There is no such thing as 
tcp/ip on a 100.

Re: [M100] RS232 Wifi Modem

[Joshua O'Keefe]

I originally bought some cabling to do serial transfers to an Amiga, and
wound up dedicating this setup to a permanent TPDD emulation setup at my
desk.  Just to record it for posterity, here are the products I use daily:

StarTech.com USB to Serial RS232 Adapter - DB9 Serial DCE Adapter Cable
with FTDI – Null Modem - USB 1.1 / 2.0 – Bus-Powered (ICUSB232FTN), Black
https://smile.amazon.com/gp/product/B008634VJY/
This is a null-wired cable with an FTDI chip and DB9 at the far end.

StarTech.com DB9 to DB25 Serial Adapter - M/F - Serial adapter - DB-9 (M)
to DB-25 (F) - AT925MF
https://smile.amazon.com/gp/product/B87RYP/
This is your typical 9-to-25 adapter

changer - DB-25 (M) to DB-25 (M) - GC25SM
https://smile.amazon.com/gp/product/B00066HP5G/
This is the usual M/M adapter, for my 102's upside down connector

Not entirely nor elegantly, but it could be part of an ungainly stack of 
adapters that works.


This is only a 9-to-25 adapter, but you still need null-modem. So if you 
were to use this you would have to add a male/female mini null-modem 
adapter:

https://www.amazon.com/dp/B001TIP9AS/
and then stick the usb adapter onto that. It would make a 5 inch long

straight back... You could do that but that's terrible.

This will work, but it's not ideal, because it's based on a Prolific 
chip instead of an FTDI chip.


But, if you already ordered this, it's ok it will most likely work fine.


I would get this cable:
https://www.pccables.com/products/00103.html

That plus the usb adapter you already got is all you need.

Unless you're talking about Android and then you also need an OTG cable. 
But for a laptop or computer with a USB-A port, that's all you need.


The cables on that Model T Serial Cable page are not random. They have a 
particular combination of wiring and connectors that most cables don't have.

Re: [M100] Why not transfer with Telcom?

[John R. Hogerhuis]

In fact sending and receiving plain text is a common use case. In
particular it's important for bootstrapping a TPDD client.

That and the existence of tsdos ROM and REX is why I've never added a
bootstrap injector to LaddieAlpha.

Plain text is not related to FTP though. Ftp is a file transfer protocol
based on TCP/IP. And there is no TCP implementation for the model 100 as
far as I know.

If you want to serve files as plain ascii one way would be to put Linux
getty on a serial port and connect to that with TELCOM. Set capture and cat
the file.

Unfortunately many programs are not plain ASCII text (BASIC is stored 
tokenized, and ML programs are pure binary) so TELCOM does not suffice.  If you 
want to transfer more than text, TS-DOS and a TPDD emulator is the most user 
friendly option.

[M100] Why not transfer with Telcom?

[AvantGuard Systems]

I can use Telcom and connect to BBS's. When on a session you have the
options to (I forget the exact terminology on the screen) UPLOAD, DOWNLOAD.

So if I can upload and download files, why can't I build my own FTP SERVER?
or whatever server, put the program files on it and download them to the
Model100?

Will I need some special program on the Model100 in order to access the

This is how you connect it:

That is the entire directions is just, ensure you have the right wiring 
in the serial cable, and these are several known-good cables you can buy 
already made, or follow that table to make your own, though the parts 
cost more than a full pre-made cable does.

There are mComm versions for Windows and Android.

dlplus targets Linux.

LaddieAlpha runs on most versions of Windows, Linux, OSX on .NET or Mono.
It even ran on Windows for a while (I don't think it does any more because
it  is compiled against newer .NET run times than existed for 98).

All do pretty much the same thing though dlplus and mComm have bootstrap
injectors. For LaddieAlpha you either use TS-DOS ROM or you have to
bootstrap with a terminal program.

Basically, you need some software on the Model T to be the client while
whatever program you pick for the other side is the server.

 Many ways.

 How to decide which of the many ways depends on what your priorities
 are, convenience or cost, and on what you have available for a modern
 machine.

 For instance one super convenient option is there is an Android app
 that
 is both a TPDD server and TPDD client installer/bootstrapper. You don't
 have to buy anything but the serial cable and usb adapter, but you
 always need that anyway. But that's only super convenient if you happen
 to have an Android phone or tablet. And I suppose only if moving files
 to a phone instead of your real computer is good enough, maybe via
 google drive.

 The generally most convenient and robust way is a serial cable and a
 TPDD emulator and a REX#.

 Whatever other software or hardware you use, you pretty much always
 need
 this cable:
 http://tandy.wiki/Model_T_Serial_Cable

 Then there are several different things you can do that are all
 different levels

For the record, I did end up successfully upgrading a 2M REXCPM to 4M 
using the RMLV3216AGSA linked below.


The only special note other than "how to desoldering alloy" and "how to 
drag solder" was that the epoxy holding the copper on the pcb is weak. 
Be exceedingly gentle wicking up the desoldering alloy, don't scrub, and 
even with gentle wiping, only move in the same direction as the the 
pads, don't wipe them sideways. Blot-lift-move-blot instead. One of the 
teeny pads for the sram shifted sideways on me even though I was being 
careful. I was able to nudge it back into place eever so carefully 
without breaking the trace and solder the new chip.


Other than that it was straightforward. The pin-1 corner is marked on 
the silkscreen, and there was nothing special to do, just solder the 
chip and load the same firmware, only using the 4M cpm file.


Thus do I publicly waive any hint of warranty on my rexcpm. ;)

Also the dlplus bootstrap option can be used for rxctst.DO too.
dl -b./rxctst.DO    and   RUN "COM:98N1EN"   and it runs all the tests 
on the rexcpm.

$26 is a lot, and I wouldn't expect you to buy 100 of them for $2400 
but, if I want it, and assuming a perfect solder job, is there 
anything else besides a reflash required to make it work?


Obviously, it's a given that all concept of warranty and liability 
goes out the window instantly.

I can already confirm that this works.

This is exactly how I did it back when I actually had time to sell 
things through Club100 (prior to having kids that is).  I manufactured 
and sold probably 2 dozen new printer cables by doing this very same 
proceedure.  I would purchase 25 foot rolls of x26 flat ribbon cable, 
IDC 26 female connectors and Centronics connectors and crimp them 
myself.  They work great.

Hi,

I think I actually did try that once and it did work but it was ages 
ago when I had a printer with a parallel port.  Wait, the HP LJ IV 
still has one it still works(30 year-old printer.) If I 
can find one of those parallel port cables floating around I can try 
and confirm it.

wat?  That's pretty neat.


Yep. But for hearing it from others and then having tried it
myself, I'd have figured it was pure Baloney Sandwich.
