TTY Insane

Hi All,

Long time reader, first time poster.

I have a tip session to a v480 serial console running Solaris 9.
Look at this mess I'm getting back...

connected root0-**root0-**root0-**li*****************************orclecro***************************tc*************** **************ltfore*****************************roceice*************************cetc* ****************************texort**************************ifl-te-Sire0-ltet**toe****************************ttitllc***********************treoerel***** *********************treoli*****************************rlot+fo**********************r ox****************************olt*****************************xfet**************************** *iirotroot0-**root0-**root0-**exort**Mt00Mt00:*i*ot**ietifierroot0-**root0-**root0-**ro

Can anyone tell me how to make it sane? stty sane made it worse!

I invoked tip using tip -9600 /dev/ttyb, as we always do. It still works fine if we plug it into another box. I have a perfectly legible telnet session to the box so I can make changes, look at stuff etc. My best guess is that there's a line speed issue but I don't know where the settings are.

Maybe enquire on the port settings?

stty -a </dev/ttyb

Hmm, interesting. Thanks for the idea.

Is it normal to have rows and columns at 0?
Anything else here look wacky?

# stty -a </dev/ttyb
speed 9600 baud;
rows = 0; columns = 0; ypixels = 0; xpixels = 0;
csdata ?
eucw 1:0:0:0, scrw 1:0:0:0
min = 1; time = 0;
intr = ^c; quit = ^\; erase = ^?; kill = ^u;
eof = ^a; eol = <undef>; eol2 = <undef>; swtch = <undef>;
start = ^q; stop = ^s; susp = ^z; dsusp = ^y;
rprnt = ^r; flush = ^o; werase = ^w; lnext = ^v;

By running:
$ tip hardwire

you get the correct seeings to tip from one Sun box to another, the settings this uses are in the /etc/remote file with the lable "hardwire" which uses ttyb to connect out of.

Thanks for the reply Tony.
Unfortunately.... same result...

# tip hardwire
connected root0-**root0-**root0-**root0-**ro

I think the problem is on the remote machine.

I would suspect the data, stop or start bits are set wrong, apart from the fact that the word "root" turns up okay!?

You could check the ttya-mode setting in the eeprom(1) on the server you are trying to connect to.

eeprom from remote machine shows the following for ttya-mode...


Is the trailing hyphen a problem?

All this worked fine until a few days ago...?
