Perderabo, thanks a lot.

After select() and if(FD_ISSET(fd, &rfds)), then I read the buffer. As you mentioned, I only can read 8 bytes one time (my full reply message is 13 bytes) by "result1=read(fd,buffer,13);" (result1=8). After I read these 8 bytes, I have to read the buffer one byte after another to get correct message. If I use "result2=read(fd,buffer1,13)" after first 8 bytes read, result2 always is 0. Is there anyway I can use multiple block reads to get a full message? Or how can I get one read more than 8 bytes in my case in one read?

input-linux-mouse

input-linux-mouse(7)							GGI						      input-linux-mouse(7)

NAME

       input-linux-mouse - Direct mouse input

SYNOPSIS

       input-linux-mouse: [<mousetype>] [,<file>] [,[b<bauds>][r<rts>][d<dtr>]]

DESCRIPTION

       This input opens a file (usually a device file or pipe) and reads mouse protocol data from it.

OPTIONS

       mousetype
	      Indicates what type of mouse is attached.  The following types are supported:

	      o   ms, Microsoft : Two button Microsoft compatible mice.

	      o   ms3, IntelliMouse, mman+ : Serial Intellimouse or compatible. Supports four buttons for mice like the Logitech MouseMan+.

	      o   MouseSystems, msc : MouseSystems compatible (used in most 3-button mice).

	      o   Logitech, logi :  Used in older Logitech serial mice.

	      o   mm, MMSeries :    MM series mice.

	      o   Sun : Sun mice. The protocol is the same as 'msc' protocol except it used only 3 bytes per packet.

	      o   MouseMan, mman :  MouseMan protocol.

	      o   BusMouse, bm : Non-PS/2 busmice.

	      o   LinuxUSB, lnxusb : IMPS2 that doesn't choke on USB (no init attempted).

	      o   ps2, PS/2 : PS/2 mice (most non-serial mice use this protocol)

	      o   imps2, IMPS/2 : PS/2 IntelliMouse and compatible (not USB, see lnxusb for that.)

	      o   mmanps2, MouseManPlusPS/2 : PS/2 Logitech MouseMan+ and compatible.

	      Most of the strings supported by GPM, SVGAlib and XFree can be specified.  If you find one that isn't, please report.

	      The  special  value  auto  tells input-linux-mouse to read ~/.ggi/input/linux-mouse, and if that fails, $sysconfdir/ggi/input/linux-
	      mouse.  If none of the two files are found, input-linux-mouse tries to auto-detect the mouse, and as a last resort  uses	the  mouse
	      information specified in /etc/vga/libvga.config.

       file   The file to read mouse protocol data from; defaults to /dev/mouse.

       baud   Baud rate of mouse device.

       rts    Turns off RTS if set to 0; turns RTS on if set to a number greater than 0.

       dtr    Turns off DTR if set to 0; turns DTR on if set to a number greater than 0.

FEATURES

       o   Generates evPtr* events.

FILES

       ~/.ggi/input/linux-mouse and $sysconfdir/ggi/input/linux-mouse consists of the following entries:

       mouse mousetype
       mdev file

       where mousetype and file has the same semantics as the invocation options of the same names.
