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...

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.

iscc(7) Miscellaneous Information Manual iscc(7)
NAME
iscc - serial communications interface
SYNOPSIS
controller iscc0 at isa0
DESCRIPTION
An onboard Zilog 8530 DUART provides AXPvme-based Single Board Computers with console (CON) and auxiliary (AUX) serial communications
ports. Both serial communications ports can operate at baud rates from B50 to B38400, excluding B134 (see tty(7)).
On AXPvme Single Board Computers configured with a graphics head as the system console, the CON serial communications port (/dev/tty01) is
available for use by application programs as an additional communications port.
In the absence of a graphics head, the CON serial communications port (/dev/console) becomes the system console. When used as the serial
system console, the CON serial communications port always operates at 9600 BPS, 8-bits, and no parity.
Regardless of system console, the AUX serial communications port (/dev/tty00) is always available for use by application programs.
RESTRICTIONS
Data communications equipment attached to the CON serial communications port must be set to 9600 BPS, 8-bits, no parity when configured as
the serial system console. The iscc terminal driver enforces this restriction.
No modem control is supported for either the CON or AUX serial communications ports.

console terminal local terminal local terminal
