* speakup serial ports @ chuckh ` Dawes, Stephen 0 siblings, 1 reply; 13+ messages in thread From: chuckh @ UTC (permalink / raw) To: Speakup is a screen review system for Linux. I can just try this, I guess. But can anyone spare me the pain? Can I use ttyS4 in speakup for a hardware synth? Is speakup_ser=4 a valid option, assuming of course there actually is a ttyS4 and a synth on it?

A simple reminder: Numbering in Linux starts with 0. So for example, if you have 2 serial ports on your computer, they are ttyS0 and ttyS1. So to ask if you can place a Synth on ttyS4 implies that you have 5 serial ports on your computer. I haven't necessarily answered your question, but make sure that you are counting correctly before you try to connect and then get frustrated because you are not counting correctly.

Hi Steve, Yes. I have a box with one serial port on the motherboard, and another on a PCI card. The first one appears as ttyS0 and has a braille display on it, and the other one appears as ttyS4, where I would like to put a synthesizer. Some software only allows ports 0 to 3, the first four ports, and I cannot recall whether that is the case with speakup.

Yep, looks like that's what we will do. The box is in a distant city though, so the user probably ought to be handy to pick up the pieces if necessary <smile>. Worst case: speakup cannot cope with ttyS4, so it reverts to ttyS0, thus hiding that port from brltty when it wants to load. No speech, no braille. That's why I thought I'd ask first.

That's why I thought I'd ask first. Why not reconfigure Brltty to use ttyS4 instead? Brltty comes up much later in the boot process, and can happily deal with pretty much any port you throw at it. I've even used it once over a USB to serial converter, but it was flaky in that configuration. Since Speakup talks to the hardware directly, it's really best to get Speakup working on the built-in serial port, as you are much more likely to succeed. ^ permalink raw reply [flat|nested] 13+ messages in thread

We foolishly tried the other way, and now must figure out a recovery strategy. I'm a lot better at figuring stuff out after it happens than I am ahead of time, unfortunately. Your suggestion is what we will try next.

Hi Kirk, Thanks. But now we have a dead system, so CPR measures are in order. Fortunately the user has a grml disk to rescue things with, so I think we can unscramble his eggs this time. I see from the boot messages that speakup is already up and talking when the PCI slots are scanned and configured, so it's no wonder ttyS4 did not work. Ain't computers fun?

Chuck, it should still be possible for you to have speakup modularized, and to load it once the pci serial card is initialized. Admittedly, this wouldn't give you speech as early as it would if speakup was in the kernel, but it should still work. Also, Kirk did say that the addresses for ports 0-4 are scanned, so speakup should still look for your synth on ttyS4 once the module gets loaded.

Hi Greg, That's a possible path too. Thanks. But I think what we'll do first is put the synth on ttyS0 and the braille device on ttyS4 and see if we can bring it up that way. I imagine Kirk meant 0 to 3, the first four ports, instead of 0 to 4. This is awkward since the user is 35 miles from here with a dead system and my wife, who loves to talk, is on the only phone we have here. So, stay tuned! <smile> Chuck On Fri, Jul 28, 2006 at 12:22:27PM -0700, Gregory Nowak wrote: > Hi Chuck and all. > > Chuck, it should still be possible for you to have speakup > modularized, and to load it once the pci serial card is > initialized.

Perhaps I'm being naïve, but could you not just specify speakup_ser=4 on the boot command line? Of course, the PCI subsystem may hnot load in time... Though iirc, you said you had modularized Speakup.

* Re: speakup serial ports ` Garrett Klein @ ` chuckh 0 siblings, 0 replies; 13+ messages in thread From: chuckh @ UTC (permalink / raw) To: Speakup is a screen review system for Linux. Garret, In this case, the speakup drivers were compiled into the kernel, since I was not using an initrd and wanted speech from the start of bootup. So speakup_ser=4 was out. But I was able to put the synthesizer on ttyS0, and use ttyS4 for brltty, which is less particular about such things. One thing I have noticed though is that when the brltty driver is loaded, the "continuous read" feature is lost. I no longer have that system here, and did not look into it further while I had it. Otherwise, everything got resolved okay. Chuck -- The Moon is Waning Gibbous (97% of Full) Only 10 kinds of people: those who do binary, and those who do not.
