+ ---help---
+ VIA High Speed Serial is a little kernel module (1 KB) which enables
+ high speed serial port modes of VIA VT82C686A or VT82C686B
+ southbridge-equipped motherboards. With this module, you can use the
+ serial port at 230400 bit/s so that you can get the full 128000 bit/s
+ from ISDN-TA. The module has been tested with both 686A and 686B
+ chipsets.
+
+ To compile this driver as a module, choose M here: the
+ module will be called viahss.

+ <title>High speed serial port for VIA VT82C686 chipsets for linux</title>
+</head>
+<body>
+<H3>Setting the serial port speed over 115,200bps</H3>
+<br>
+If you have motherboard which has VIA VT82C686A or VT82C686B chipset
+you can set serial ports in high speed mode with this kernel module.
+I use module with external ISDN-TA and haven't had any problems
+so far but I cannot guarantee that you won't have buffer overflows if
+you use full 230K or 460K speed all the time (FIFO's are still 16550A size).
+ISDN with two channels maxes out at 128 Kb which means that it doesn't
+really stress serial ports at 230400. Unlike SHSMOD-patches you don't have
+to patch serial driver and module takes only 1KB of memory when it's
+loaded which should leave enough room for other programs. It should
+be also possible to make this work from userspace but accessing
+pci devices is so much easier from kernel.
+
+<H3>How to use module</H3>
+Get the <A href=http://www.kati.fi/viahss/viahss-0.92.tar.gz>package</A>
+and compile it using included makefiles.
+<H3>For 2.4</H3>
+If you have kernel in some other location than /usr/src/linux edit Makefile
+before compiling. You can also install module with "make install". After
+you have loaded module in kernel (use modprobe or insmod) you can set serial
+ports to use high speed modes with setserial.<br>
+<H3>For 2.5/2.6</H3>
+Copy Makefile-2.6 on top of Makefile and do make. After loading module set
+serial speed with setserial. (NOTE: This gives a warning on depracated
+method).
+
+<br>
+# setserial /dev/ttyS0 spd_cust divisor 0x8002
+<br><br>
+which sets COM1: speed to 230400. With 0x8001 you should get 460800
+but I haven't tested it. If you want to use COM2: use ttyS1 instead of ttyS0.
+
+After this you should set program which you are using to use 38400 bps
+speed which is now actually 230K or 460K. For more information check
+setserial man page (spd_cust).
+
+You can use serial port work as normal if you do<br>
+<br>
+# setserial /dev/ttyS0 spd_normal <br><br>
+After this you can also remove viahss module with rmmod if you need to. Module doesn't intefere with normal serial port usage so you can leave
+it loaded if you don't need that extra 1KB which module uses.
