speakup, grml and braille blazer

speakup, grml and braille blazer

[Cody Hurst]

Hello all,

   I just realized I could whip up an external synth with a db25  
serial cable, a converter and a db9 serial cable, however when I boot  
grml I use this boot command

grml speakup_synth=bns, ttyS0 and get no speech. On the blazer's  
speech config menu I set it from parallel to serial. however I tried  
starting grml with it on serial and parallel and still no speech. I  
know this can be done but I just don't know how. I'd like to know what  
I"m doing wrong here. Thanks for any hep.

What do you mean by "converter"? If you're talking about a usb to
serial converter, then you're out of luck, since speakup doesn't
support those as of now. If you mean some kind of other converter,
then you'd better explain. Also, do you have a null-modem adapter in
that cable chain? If you don't, and if your cables are standard
straight-through cables, then you need a null-modem adapter.

I don't know the state of speakup in grml, if it's pre-git speakup,
then you're fine, but see below. If grml has speakup from git, you
need to specify the synth as speakup.synth=bns, assuming grml has the
bns synth built into the kernel.

I don't know where you got the ttyS0 from; this isn't how you specify
serial ports in speakup. If the blazer is on your first serial port,
you don't need to tell speakup which port to look on. If the speakup
in grml is pre-git, then speakup will find the bns on any of the other
standard serial ports, if it isn't hooked up to the first serial
port. If the speakup in grml is from git, I seem to recall Kirk saying
that speakup from git doesn't auto-probe beyond the first serial port
anymore. If that's correct, then read up in the speakup docs how to
specify the serial port. Off the top of my head, the second serial
port would be specified with speakup from git as speakup.ser=1, but
don't quote me on that.

 and get no speech. On the blazer's speech

Ok, in the blazer's speech menu, set the port to serial. In the
printer config menu, make sure the port is set to either off, or
parallel. In the serial config menu, set baud rate to 9600, bits per
character to 8, stop bits to 1, parity to none, and handshake to
either software , or hardware. I've found that pre-git speakup at
least acted quirky with the bns regardless of what handshaking is set
to, though Kirk has said in the past that handshaking with the bns
driver should be set to hardware. I haven't tested to see how speakup
from git does with the bns. Finally, make sure the blazer is
online. Hth.

Re: speakup, grml and braille blazer

[Cody Hurst]

Hey Greg,

   The cable converter I am using is a female db25 to a male db9. I  
hope this mixing of cables is not an issue. Usb is not in the equation

For the record I am using grml 1.0, and I have gotten a double talk to  
work with it and I did specify the ttyS0 but perhaps that wasn't  
necessary. I can't remember. I will set those other commands in he  
printer config menu. I believe the printer is already set to parallel.

I will do some more testing and report on what I have found. But  
thanks for all the help, very through and consice.

THX,
Cody

Hey Greg agian,

Just checked forgot to comment on this but I actually just looked, and  
I found 2 null modem adapters serial female db9 on one end and an rj11  
on the other. Found 2 of them. What would I need this for?

I seem to recall adapters like this were/are used to connect a dectalk
express to the pc. They would be of no use to you for connecting the
blazer to the pc. Kerry described the cabling you need, and I have
nothing else to add to that. If you still have more questions though,
ask away, and we'll see what we could do for answers.

Cody,

Speech should be set to serial. Also, it's speakup_cer=0.

Your problem might be not having a null modem adapter, they're available
at raido shack for about $6.

the blazer requires a null modem cable to connect it to the computer not a 
straight through serial cable.

Well I have a db9 null modem cable, but how would I do this  
configuration? the db9 end will not fit on the blazer and vice versa.  
More insight on this would greatly be appreciated.

Re: speakup, grml and braille blazer

[Kerry Hoath]

put a gender changer on the blazer to change the serial port from female to 
male on the blazer.
plug a 25-pin female to 9-pin mail into the converter.
plug the null modem from converter to pc.

You could also get a 25-pin null modem cable; gender bend the blazer end 
then convert it down to 9-pin on the pc end.

the cable needs to be null modem and you need things of the right gender as 
the port on the blazer for serial is female.

When I plug the rj11 end of the cable to the pc, how do I tell speakup

most modems?

Re: speakup, grml and braille blazer

[Kerry Hoath]

don't confuse a null modem with a modem.
A modem is a device that lets your computer talk over phone lines.

You should not have any rj11s near your bns; only serial cables.

There are 2 layouts most commonly used for serial ports, the pc style (dte) 
and the modem style dce.
The blazer has a pc-style wiring on it but the gender is female.
You need to connect pc to pc so you need a null modem.
This is like in nedworking where you wish to connect pc to pc with no hub or 
switch you need a cross-over cable.

A null modem is a device or cabling wire map that allows 2 computers to talk 
to each other over a serial link.
Assume we have 2 computers with a 9-pin serial connection wishing to talk to 
each other.
The cable in use is a straight through. Pin 2 is transmit and pin 3 is 
receive and 5 is signal ground.
If the pins are wired straight through then the transmit and receive pins 
are wired transmit to transmit and receive to receive.

This will not work as the transmit pin on one computer needs to be wired to 
the receive pin on the other. A null modem or cable does this for us.
Usually it's wired as
2 to 3, 3 to 2, (transmit to receive)
5 straight through (signal ground)
4 to 6, 6 to 4, (cts to rts)

Then cd is tied on one end to dsr and possibly dsr.

Re: speakup, grml and braille blazer

[Cody Hurst]

Then I probably don't have what you are alluding to. The only cables I  
have are a parallel db25 with male connectors on each end, and a db9  
with female on each end. I am connecting the two via a converter that  
converts parallel db25 to a male db9. I can't just connect one to ther  
other, without this connecter I can't do anything. What would I do now  
since I probably don't have the cable you are refering to?

Re: speakup, grml and braille blazer

[Kerry Hoath]

The db9 with a female on each end should be a null-modem cable.
You need to get a 25-pin gender changer for the blazer;

put a 25-pin female to 9-pin male on the blazer, connect your 9 to 9 cable 
from that to the pc.

Cody, you don't want a null-modem with an rj11 connector on it, it
should have a female connector on one end and a male on the other.

Null modem isn't an RJ11 cable...It's an old term for a special kind of 
serial cable, used to connect two like devices together, for instance, a 
direct RS232 connection between two machines.  One comes with the BNS 
interface kit.

Nick

Hey,

   I have fixed this issue. I also found an old din cable for the bns  
I have here. I have my embosser talking and everything is cool now.
