Testing a synthesizer

Testing a synthesizer

[james collins]

I tried this command at the command line. When I ran it my cursor  
moved down a line and I was able to type words and then I would hit  
return, but my doubletalk wouldn't talk. I am trying to test my  
doubletalk synthesizer. I bought a USB to serial adaptor cable, I am  
using it with a doubletalk speech synthesizer. Just wondering why I  
can't get my doubletalk to talk? Any help would be appreciated.

The command would be:

echo "text" > /dev/ttyS0

...but the hal daemon might get in the way.

Try using setserial to first setup your serial port.
Also check that /dev/ttyS0 is actually the port you want to address.
Check dmesg output or /var/log/messages for info on what the correct port 
might be.
This is general, I do not have that synthesizer, but have done such 
testing using others.

If you have a USB2serial adapter, this command will never give any
result. This is what you want:
echo "text" > /dev/ttyUSB0

I ran the command you gave me and my computer said

-bash: /dev/USB0: Permission denied

I tried putting sudo in front of the command, but got the same result.

Did you write it as I have written?
I miss "tty".

Re: Testing a synthesizer

[james collins]

Just tried it with TTY got the following

-bash: /dev/ttyUSB0: Permission denied

Can I type sudo before I give this command, and then when my computer  
asks for my password give it and then for like 5 minutes I would have  
permission to run this command?

Should work at least on a real Unix/Linux; but, again, I don't know
anything about Macs.
And there's one more thing you can do:
Try whether the following command exists:
lsusb
of course with your usb2serial cable connected.
Is it listed? Do you know the exact type of cable?
Can you get sighted assistance for a while, to look in Mac's device
manager whether this cable has been detected at all?
Provided there's such a thing like a device manager on this machine.

I don't know if I am logged as a root user for some reason I don't

sudo

but all I got back was usage for the sudo command. How would log in as  
root to run the command you gave me?

If you know the root password, the command:
su -
should ask you for the root password.
note it is su space dash

Re: Testing a synthesizer

[Cheryl Homiak]

First of all, if you are running Macosx as you said you were on the  
brltty list, you need a driver for the serial-usb cable.

Second, the ports on the Mac are not named the same as in linux.  
Usually it would be /dev/cu. with something after the period; for my  
prolific cable it's /dev/cu.usbserial but for my keyspan I've had  
different designations like /dev/cu.USa19H1d1P1.1 Once you have he  
driver installed an dhave the cable and device plugged in, you can run

ls /dev/cu.* and see what your choices are.

If you are not running Macosx but have put some other unix system on  
your Mac, see the documentation for that system.

 From what I was told by the company that makes the USB to serial  
adaptor, I don't need a driver for the os I am running mac os x 10.5.7  
the person I had talked from the company had me go to my apple menu  
and there was a listing under USB that said something like USB-serial  
the person I talked to said that the adaptor cable is alright.

That would be

ls /dev/cu then a period and then an asterix *?

Re: Testing a synthesizer

Hi James, have youchecked the permissions on /dev/ttyUSB0?  You may not
have write permissions on the device.  I have a couple of usb to serial
addapters, and they work just fine, although they don't use the standard
serial device addresses and interrupts, which is whay speakup won't work
with usb serial devices.  Hope this helps.

Re: Testing a synthesizer

[Cheryl Homiak]

Well, all I can tell you is that I have never had a usb-serial cable  
that did not require a driver and I've had two of them. Certainly one  
may have come out that does not require a driver or an update might  
have allowed usb-serial without a driver. But the information in my  
last post still holds true; the device names will probably not be the  
same as in linux.

Re: Testing a synthesizer

[Cheryl Homiak]

That means you probably do need a driver; did your cable come with a  
cd and is there any documentation about installing it on the Mac on  
the cd? What manufacturer shows up in System Profiler for your  
usbserial? System Profiler is what you were opening when you earlier  
described going into your menus and finding it. Also, I assume you did  
your ls command with the cable plugged into the Mac.

The cable is made by dynex, I actually downloaded a mac driver, but

system. Was also told that there wouldn't be any harm in installing  
it, but I don't know?

Re: Testing a synthesizer

[Gene Collins]

James, to find the location of your usb addapter, try this.  at a shell
prompt, after you have disconnected and reconnected your usb to serial
addapter, type sudo dmesg.  This will display the boot messages on the
mac, and any disconnect and reconnect messages from the usb system. 
Read the last 3 or four lines of output, and see if you don't see the
device the serial device has been assigned to.  I'm not a mac user, but
I have checked, and I know the mac does support the dmesg command, which
must be run as root.  If the usb device doesn't show up, then you may
indeed need a driver.  The problem is that some devices need special
drivers, and others are supported natively by the kernel.  Hope this
helps.

Re: Testing a synthesizer

That is one of my big questions, what is the designation of my serial  
port? The geek squad agent couldn't tell me. And I have been told  
various names like s0, usb0 cu.usbserial etc. Someone from this  
mailing list told me of a command that I might be able to use, and I  
am thinking on calling apple, but they don't have support for a lot of  
stuff like programming, the command line etc.

Re: Testing a synthesizer

[Cheryl Homiak]

The idea of using dmesg is an excellent one. But you will need to run  
it with sudo unless you have a root password set up and can run it as  
su.

Also, check to see if you have a /de/tty.usbserial.
It is true that some devices are supported in the kernel; the two usb- 
seial cables i've used have to have drivers but you might have hit on  
one that doesn't require a driver. What's tricky here is that the  
brand name of the cable doesn't necesssarily match with the name of  
the actual cable sometimes. for instance, my prolific cable actually  
is the cable sold by several different vendors. My keyspan, on the  
other hand, is definitely keyspan.

The last four lines from dmesg are:

Wake reason = UHC3
System Wake
Previous Sleep Cause: 0
USB (UHCI):Port 2 on bus 0x5d has remote wakeup from some device

Don't know what the location of USB adaptor is from this? Any help?

You meant /dev/TTY.usbserial right. I checked in /dev with synthesizer  
plugged in, but couldn't find tty.usbserial I did find ttys0 though.

Re: Testing a synthesizer

[covici]

Why not try the following:  And this may be difficult, but if you can
get to be root, see if there is a /var directory and then /var/log.
Now, I am not sure what file to tell you to look in, but it might be
called messages, or maybe syslog, but you will just have to poke.  Now
when you find the file with recent log messages, plug your cable in and
see if there are any changes, also look in dmesg to see if anything
happens.  If nothing happens in anything in /var/log, then you need a
driver.

Hope this helps.

Re: Testing a synthesizer

[Cheryl Homiak]

I'm way behind in my mail today so if you've already solved this, just  
ignore.

I did some googleing--google is your friend. I didn't do it sooner  
because I thought you had probably done so before posting but I should  
know always to google and never to assume. At any rate, it does appear  
that your dynex has the prolific chip, with which I am quite familiar  
having used it extensively. It does appear to need a driver unless  
something has changed since 2008.

There are two sources for a prolific driver, well three if you count  
just using your cd. Your choices online are as follows:

http://www.prolific.com.tw/eng/downloads.asp?ID=31

There are lots of drivers shown on this page so be sure to get the one  
that is a universal binary; I believe it's the first one after all the  
Windows drivers. If you download this .dmg file, and follow the  
instructions, you should have the driver working as /dev/cu.usbserial  
and/or /dev/tty.usbserial. I've usually used the cu one but I can't  
remember whether or not it matters.

Your other choice is found at sourceforge:
http://osx-pl2303.sourceforge.net.
I don't think I've used this one though some posts I read said it  
worked; it's not clear to me if the driver shows up with the same  
device names I've listed above or not but if you use this driver you  
can use the method of plugging in your cable and checking dmesg using  
sudo.

Hth.

Re: Testing a synthesizer

[james collins]

Assuming I don't need a driver for my USB to serial adaptor cable, are  
you saying the command you gave me

ls /dev/cu.*

Will give me a list of devices, and I should be able to find the name  
of my cable from the list? And then I could run the command

echo "text" > /dev/ttyUSB0

Substituting ttyUSB0 with the name of my cable? I am currently trying  
to figure out how to login as root user, so I can run the echo command  
to test my synthesizer. Thanks for the help so far, btw when my USB to  
serial cable is plugged in, I can go to the apple menu then more info  
and under USB there is a lot of info, like it says:

USB-Serial Controller
It also mentions the name of a driver and it also has pci device Id:  
0x2831

I don't know if that means anything, or not?
