New page

== Short ==

A way to use an old PC as a docking station for your Model 100 or 102. It will probably work with a 200, too.

== Introduction ==

My ideal was that I could transfer files from the laptop to the PC, and back. That's not really a problem: use Desklink and teeny. Configure the PC with DOS, put Desklink in the autoexec.bat and voila: instant TPDD-emulation. If that's all you want, you can stop reading here.

Problem is, what do you do with the files when they are there? Or, how do you get a file from your internet-PC, via the old PC with the TPDD-emulator to the Model T? Typically it's like this: you put the file on a diskette, you attach a keyboard and monitor to the old PC, you boot - interrupting the autoexec - you copy the file in the \ROOT directory, you take keyboard and monitor away again, you boot up, and let Desklink take over the PC. Until the next time you have to transfer a file to or from your laptop. Not practical and a lot of hassle.

So you need a setup to operate in two modes: TPDD-mode, where the PC acts like a TPDD-drive and stores all your files. And CONTROL-mode, where you control the PC to transfer files to and from the outside world. And you need a way to switch from one to the other.

Solve problem one: keyboard and monitor. The hassle of always switching stops the PC from being a real docking station. Of course, you could leave the keyboard & monitor attached, but then you still have "a Model T attached to a PC", and not, like I wanted, a Model T in control of the PC.

There is a way to direct console input/output to the laptop: using the DOS CTTY command. CTTY can redirect I/O to the serial output, for use with any serial terminal, like a Model T. So, issue the command CTTY COM1: on the PC, and set the model 100 to TERM in TELCOM, and there you have it: a C:\-prompt on your model 100, and you are in control of the PC, without keyboard or monitor. Text only, enough for basic file handling, and you better not call up any large listings, but it works.

Solve problem two: Desklink. Once you have started Desklink, how do you get out ? You have to get out because you want to go into CONTROL-mode, to control the flow of files. Sure, press F10 or CTRL-C. But you can't do that, because you have no console at that moment, because your laptop is running TEENY, or FLOPPY, or TS-DOS, ... And when you're out of these programs, Desklink is even less responsive. So the only way to get out of Desklink on a PC without keyboard, is pressing RESET on the PC.

And then you're rebooting, entering the AUTOEXEC again ... Wait ! What if you turned the order around ? I may sound obvious, I may even be stupid, but it took a while before I figured that out: first enter CONTROL-mode, then enter TPDD-mode. And to get back to CONTROL-mode, press reset on the PC, and run TELCOM on the Model T.

Below, we put the above scheme in practice.

Hardware you need:

- of course, your Model T
- a DOS-running PC with a serial port. Ideally, any old one between a '386 an a Pentium II. Faster PCs could cause timing errors. If they do, look at Steve Adolph tips for slowing down your PC. http://bitchin100.com/wiki/index.php?title=How_to_set_up_an_old_PC_to_run_LAPDOS
- it has to be a PC with a reset button.
- a working, crossed serial cable between the two machines, the PC and the Model T

1. Configure your PC
- The only limiting factor is the PC's ability to run Desklink. Fastest one I used was a Pentium 75, and that was OK.
- Configure the BIOS in such a way that the machine can boot without problems without monitor, keyboard or mouse attached.
- Install DOS. Any DOS should do, but don't use Windows. MS-DOS 5.0 is a good choice, because of its enhanced memory management capabilities and small footprint. I've also used PC-DOS 6.3, but my favorite - I want to limit MS-payware - is the free Caldera DR-DOS 7.02. The example files below are written for that version.
- install DESKLINK in an new directory C:\PDD2
- create a subdirectory C:\PDD2\ROOT

DIRECTORIES
Here is (simplified) tree of my C:-drive.

path
c:\
+---sd
+---bat
+---zip
+---pdd2
| \---root
\---drdos
+---ini
\---tmp

- use the following CONFIG.SYS

1. DEVICE=C:\DRDOS\EMM386.EXE MULTI DPMI=ON FRAME=NONE
2. DEVICE=C:\DRDOS\DPMS.EXE
3. DEVICE=C:\DRDOS\SETVER.EXE

8. FCBS=4,4
9. LASTDRIVE=P
10. HISTORY=ON,512,ON
11. COUNTRY=32,,C:\DRDOS\COUNTRY.SYS
12. DOS=HIGH,UMB

Most of the commands are standard DR-DOS. Line 11 sets the country code (32 for Belgium, use 1 if in the US, or remove the line).

- use the following AUTOEXEC.BAT

1. @ECHO Off
2. PATH C:\;C:\DRDOS;C:\BAT;C:\SD;..
3. KEYB BE+
4. VERIFY ON
5. PROMPT $P$G

29. pause

Most of it is again standard DR-DOS. I always place my BATch-files in a separate \BAT-folder. SD is StupenDOS (2.0), the smallest file manager I know. Line 3. installs the belgian keyboard-layout. Remove or change as appropriate. In line 10. I define the directory C:\PDD2 as a new drive E:. in the root of E:, is the DESKLINK program. 12. sets the serial port to the correct bausrate. 13. switches the PC to 40 chars/line. 14. switches from video-output to serial-output. If there is no terminal program listening, the batchfile stops there and waits. So, if you have your Model T hooked up, you enter TELCOM, you set STAT to 38n1N, and you enter TERM. Lines 15. to 21 wipe the screen, and 22. to 28. put up a message. Press any key to continue, and you have control of the machine, in DOS.

- extra batchfile 1: switching to TPPD-mode: PDD.BAT

1. @ECHO OFF

3. ECHO. Press Enter, leave TELCOM and
4. ECHO. launch your PDD File-utility.

By then, you should be out of TELCOM and into TEENY.

- extra batchfile 2:
If you ever have started your PC and stopped the autoexec to work on the PC, it might be in a weird state. You can also executee this batch-file if you want to release your PC from CONTROL-mode.

1. @ECHO OFF
2. ECHO.
3. ECHO. Resets console to standard display and
4. ECHO. keyboard and to 25 lines by 80 chars.
5. ECHO.
6. @ECHO ON
7. MODE BW80
8. CTTY CON:

2. configure your Model T.
- Install the DOS/disk-client. I've used teeny all the time, though I would prefer FLOPPY for the TPDD2.

Anyway: the setup I'm describing is NOT auto-configuring/loading the DOS-client, so that has to be done before. You can use the PC for that purpose, but it will have to be fully independant.

3. practical
- hook up the Model T and the PC with the serial cable
- turn on the PC
- turn on the Model T
- enter TELCOM, set STAT to 38n1N, and you enter TERM
- on screen you'll see:
+------------------------------------+
! HD for TRS-80 Model 100, Tandy 102 !

! Type PDD to emulate a TPDD2 !
! Press RESET-button to return to !

+------------------------------------+
Press any key to continue
- press any key, and you get a DOS-prompt C:\. Remember DOS? You can access A:, and copy files to and from C:\PDD2\ROOt or E:\ROOT (same place)
- start TPDD emulation with DESKLINK by executing PDD.BAT: you're now in TPDD-mode
- get out of TELCOM, and use your Model T with the DOS/disk-client of your choice.
- If you want to leave PDD-mode you have to press the reset-button on your PC.
- If you want to stop: simply turn off the machine. (may be not a good idea when using an XT where you have to 'park' your HD..)
- You can also get out CONTROL-mode by using RTTY.BAT, and then turn off the PC.
