XF86 xterm on IRIX acts the same way. We had no clue why ssh:ing to a
solaris box from an IRIX xf86xterm resulted in signal 1.. Now we do.

xf86xterm sets speed to 0 if run locally (which results in sig1).
Changing to >0 makes it work.

rxvt sets it to 38400 with the following...

# ifdef TCSANOW                 /* POSIX */
#  define GET_TERMIOS(fd,tios)  tcgetattr (fd, tios)
#  define SET_TERMIOS(fd,tios)          \
        cfsetospeed (tios, BAUDRATE),   \
        cfsetispeed (tios, BAUDRATE),   \
        tcsetattr (fd, TCSANOW, tios)
# else
#  ifdef TIOCSETA
#   define GET_TERMIOS(fd,tios) ioctl (fd, TIOCGETA, tios)
#   define SET_TERMIOS(fd,tios)         \
        tios->c_cflag |= BAUDRATE,      \
        ioctl (fd, TIOCSETA, tios)
#  else
#   define GET_TERMIOS(fd,tios) ioctl (fd, TCGETS, tios)
#   define SET_TERMIOS(fd,tios)         \
        tios->c_cflag |= BAUDRATE,      \
        ioctl (fd, TCSETS, tios)
#  endif
# endif
# define SET_TTYMODE(fd,tios)           SET_TERMIOS (fd, tios)

Thankyouthankyou for finding this.
