During investigation Opensolaris bug 6824625. The root cause is the different result of calling tcsetattr() for pty on Solaris and Linux.
Solaris and Linux treat slave pty differently.
For opening pty (Pseudo Terminal), there have two steps, open master device and slave device sequently. On Solaris, master pty device is not regarded as a terminal device. it regard slave device as a terminal device only.
But On Linux(I tested on Ubuntu), both master and slave devices are regarded as terminal devices.
So, tcsetattr() can work for both master and slave device on Linux. But, tcsetattr() can only work for slave pty device on Solaris. You can also use isatty() to tests if file descriptor is associated with terminal device .
It’s a useful tip for porting terminal application between Solaris and Linux.
A piece of code for your reference, how to open pty: You can see that ioctl() only apply to slave device on Solaris(in macro #ifdef __sun).
FYI.

Concept of pty, tty..(in Chinese)

http://blogs.sun.com/weixue/entry/which_terminal_emulator_do_you
During doing many terminal(emulator) evaluation, I found there are so many terminal emulator. And most of these support i18n feature. That means you can use it to display of input international languages character. Currently, the goal of evaluation is to weight which terminal should be high priority to be integrated in Opensolaris. Of course, there are some terminal emulator are not be listed. such like iterm, fbterm. If you need, I’ll add them. Please see FOSS terminal evaluation. Hope you could leave comment to let me know which terminal is you favorate and which terminal you would like to be integrated in Opensolaris.
Your comments would be appraciated. Btw, if any xi18n support terminal I haven’t listed , please let me know!.Thanks!

During investigate Opensolaris bug 6824625(And 6728611 ) . There is a issue about macro Xorg, the Xorg seems to be a remnant of old Imake world. For example, in app/luit/sys.c, it always use #ifdef SVR4 as switch. but on Solaris there is no pre-define for "SVR4", only pre-define "__SVR4". (check : CC -xdumpmacros -c dummy.c). For resolve this issue, X team support a header file <X11/Xosdefs.h>. So please include this header file in the program which need use CC or gcc pre-define macros. In Xosdefs.h:
#ifdef sun
/* Imake configs define SVR4 on Solaris, but cc & gcc only define __SVR4
* This check allows non-Imake configured programs to build correctly.
*/
#if defined(__SVR4) && !defined(SVR4)
#define SVR4 1
#endif
#endif
This issue also be discussed in xorg mail-list early (Some portabity issues). Alan gave the solution on Solaris.
