Summary: Platform definitions on Solaris

Dear maangers,

thanks for your replies (less than usual). :-)

I googled some more and finally found that the replacements would 
probably be:

    // cfmakeraw(&options); // <--- not available on Solaris, so we 
better do it manually
    // begin of cfmakeraw replacement
    options.c_iflag &= 
~(IGNBRK|BRKINT|PARMRK|ISTRIP|INLCR|IGNCR|ICRNL|IXON);
    options.c_oflag &= ~OPOST;
    options.c_lflag &= ~(ECHO|ECHONL|ICANON|ISIG|IEXTEN);
    options.c_cflag &= ~(CSIZE|PARENB);
    options.c_cflag |= CS8;
    // end of cfmakeraw replacement

    // cfsetspeed(&options, speed);   // not available on Solaris, so we 
better do it manually
    // begin of cfsetspeed replacement
    cfsetospeed(&options, speed);   // Set 9600 baud
    cfsetispeed(&options, speed);   // Set 9600 baud
    // end of cfsetspeed replacement

Special thanks to Dale Ghent <daleg@elemental.org> who outlined that we 
can use

	touch foo.h; cpp -dM foo.h

to get a list of defined macros on each platform. It seems that

#ifdef __sparc
...
#endif

would be it.

Thanks a lot!

Regards,
