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. Basically, this is developed for ISDN-TAs, which at least in europe are constrained by the normal serial port speed of 115200 bit/s. 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. Functionality is the same as with SHSMOD patches, but you don't have to patch the serial port driver.
