Sorry for my non-native(may be broken..) English.

Important notice
In the first time, the SHSMOD was the little 1 page program which was made in just little time for the private use.

But it is growing up continuously.
I can't support it anymore.

I stop using it myself.
The chips which I don't have increased.
I receive query/request mails everyday.

I looked for the person/company that take over the SHSMOD.
Now, I found the company that be build by a friend.
The SHSMOD is transferred there. I don't touch it at all after the switch over.

I will try to ask the function of the present equivalent handled as reportware. But, a promise can't be done.

When it becomes a product, I thinks that the requests, support of the new chip,
coexistence with the built-in modem with NS, WinBond,
NT Version,
will be supported.

If you have interesting about bundle SHSMOD with your product, Please mail to me. It is transferred to my friend.

It is not widely known, but the serial ports on motherboards and add-in cards that use the some I/O controllers will support operation at greater than 115200 bps.
I checked mother boards in Akihabara electric town and local PC stores. The I/O controller chips was used with 90% or more of the newest mother boards.

All they need is the proper software to enable and program these high speed modes. That is what this page provides.

M1543(Aladdin IV+,V south bridge)
Serial ports provided by these chips will run at 230400 and 460800 bps.

Serial ports provided by these chips will run at 230400/460800/921600 bps.
