Introduction

Max baud rate of general serial ports is 115Kbps. But, its rate is not enough to use MP on ISDN. Over 115Kbps is needed.

So, I have made a patch for serial driver that supports some high speed serial boards. After appling the patch, sio driver allows over 115Kbps on high speed serial boards.

About the patch

The patch supports following boards.

Vendor	board's name	Allowable baud rate, over 115Kbps
VScom	200 PCI	153600, 184320, 230400, 307200, 460800, 921600bps
I-O DATA DEVICE,INC.	RSA-DV/S	153600, 184320, 230400, 307200, 460800, 921600bps
I-O DATA DEVICE,INC.	RSA-DVII/S	153600, 184320, 230400, 307200, 460800, 921600bps
ZyXEL Communications, Inc.	SP111AT	230400, 460800, 921600bps
PLANEX COMMUNICATIONS Inc.	FS-460	230400, 460800bps
American Megatrends, Inc.	S-650	230400, 460800bps
Lava Computer MFG. Inc.	Dual-650 PCI	230400, 460800bps

(The VScom 200 PCI board is supported by 3.2, 3.3 and 3.4-RELEASE patch.)
