So, you are running `tip' on the OI computer, using it to connect to the microcontroller over the serial line. `tip' uses the /etc/remote file to configure the connection. See `man remote' for information. Are you connecting through /dev/cua/a or /dev/cua/b? Those are the first two serial ports for calling out to another system. For logging in, they are named /dev/term/a and /dev/term/b . > I have two native forths that run on the MCU but w/ different > handling of NL & CR in the output. > On one I'm missing the CR, so the output from line to line moves > across and down the terminal window. `tip' is supposed to behave like an ASCII terminal, sending a CR when you type the [Enter] key. The remote system is supposed to echo the line as you type it, and then add a LF. Something's wrong here. > I *expect* "opost onlcr" in /etc/ttydefs to fix this, but it seems > not to have any effect. When does /etc/ttydefs get read?

No, that file is only read by `ttymon', the daemon that handles serial port logins. I assume that the microcontroller is not logging in to the OI computer. > The more I read, the more confused I get.

No, that's not necessary. `man tip' should have useful information. -- -Gary Mills--refurb--Winnipeg, Manitoba, Canada- ___ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
Re: [OpenIndiana-discuss] tip & ttydefs questions
I read the man page for remote as saying that what is sent *to* the remote host for end-of-line is '\n' by default. It's what is coming back, but not playing well w/ the terminal window. Certain changes to /etc/remote seem to have no effect. However I still don't know when that gets read. But even removing and reinstating the service doesn't seem to help. The problem is: ok ok ok instead of: ok ok ok FWIW the Sparc boot monitor is in forth. I've asked the author if the behavior is readily changeable. That is w/o reassembly. Though I'll do that if I have to. I have two forth interpreters that run on the MCU. One works fine. The other doesn't. You're *supposed* to be able to adjust for such behavior. That's what all the terminal and line discipline code is for. But Solaris got it badly wrong. There are so many pieces to the puzzle it's ridiculous.

Re: [OpenIndiana-discuss] tip & ttydefs questions
Have you looked at your /etc/remote settings? Might be something there? Why do you need DOS new line? Is there something on the controller that can be configured? #man remote . . . pr (str) Character that indicates end-of-line on the remote host. The default value is `\n'.

Re: [OpenIndiana-discuss] tip & ttydefs questions
Thanks. I'll give that a go. Kermit simply showed what I already knew. I'm getting a newline but no carriage return. Kermit will map a carriage return to a newline, but not a newline to the pair. Strangely stty will not allow me to change certain things, but the man page gives no indication of when or why. Evi Nemeth et al after remarking that it adds great complexity w/ little increase in functionality conclude the section on setting up terminals under Solaris w/ "Have fun." It's ridiculous that something so trivial would be such a hassle. sigh.. --- On Mon, 9/3/12, Joshua M. Clulow wrote: > From: Joshua M.

If you have GNU screen available you might give that a try -- I'm pretty sure there's a binary package in the repository. e.g. http://embeddedfreak.wordpress.com/2008/08/12/using-gnu-screen-to-debug-your-serial-port/ -- Joshua M.

[OpenIndiana-discuss] tip & ttydefs questions
I'm playing w/ a microcontroller (MSP430G2553) which communicates via RS-232 using a Keyspan USB<->RS-232 adapter and tip. I have two native forths that run on the MCU but w/ different handling of NL & CR in the output. On one I'm missing the CR, so the output from line to line moves across and down the terminal window. I *expect* "opost onlcr" in /etc/ttydefs to fix this, but it seems not to have any effect. When does /etc/ttydefs get read? Is what the remote computer sends back input or output relative to a terminal window? Should this be set via stty? I've tried that also w/o detectable effect. The more I read, the more confused I get. So far as I can tell, I can't configure the port as only an outbound connection, but must run login on it. Harmless, but annoying. But there are so many programs involved nothing is clear. Suggestions? I'm about to build kermit, which will probably solve things. I realize this has always been a can of worms. My canonical test of new sys admins was to mention modems. If they flinched I knew they were experienced. But it annoys me that I can't make tip do what I want. Have Fun!
