The jumper labeled CLK X8 provides a means to select baud rates in a higher range. When a jumper is 
not placed on the out the CLK X8 position, the baud rate range is up to 115,200 baud. When it is in the 
CLK X8 position, the baud rate range is up to 921,600 baud. 
 
Interrupts

 

Please note that, in WindowsNT, changes must be made to the system registry to support IRQ sharing. 
The following is excerpted from "Controlling Multiport Serial I/O Cards" provided by Microsoft in the 
MSDN library, documentid:mk:@ivt:nt40res/D15/S55FC.HTM, also available in the WindowsNT Resource 
Kit.  
  
The Microsoft serial driver can be used to control many dumb multiport serial cards. Dumb indicates that 
the control includes no on-board processor. Each port of a multiport card has a separate subkey under 
the HKLM\CurrentControlSet\Services\Serial subkey in the registry. In each of these subkeys, you must 
add values for DosDevices, Interrupt, InterruptStatus, PortAddress, and PortIndex because these are 
not detected by the Hardware Recognizer. (For descriptions and ranges for these values, see 
Regentry.hlp, the Registry help file on the WindowsNT Workstation Resource Kit CD.) 
  
For example, if you have an eight-port card configured to use address 0xFC00 with an interrupt of 05, the 
values in the Registry are: 
 

 

PortAddress = REG_DWORD 0xFC00 
Interrupt = REG_DWORD 5 
DosDevices = REG_SZ COM3 
InterruptStatus = REG_DWORD 0xFC40 
PortIndex = REG_DWORD 1 
Indexed = REG_DWORD 0 
 
Serial3 subkey:

 

PortAddress = REG_DWORD 0xFC08 
Interrupt = REG_DWORD 5 
DosDevices = REG_SZ COM4 
InterruptStatus = REG_DWORD 0xFC40 
PortIndex = REG_DWORD 2 
Indexed = REG_DWORD 0 
 
Serial4 subkey:

 

PortAddress = REG_DWORD 0xFC10 
Interrupt = REG_DWORD 5 
DosDevices = REG_SZ COM5 
InterruptStatus = REG_DWORD 0xFC40 
PortIndex = REG_DWORD 3 
Indexed = REG_DWORD 0 
 
Serial5 subkey:

 

PortAddress = REG_DWORD 0xFC18 
Interrupt = REG_DWORD 5 
DosDevices = REG_SZ COM6 
InterruptStatus = REG_DWORD 0xFC40 
PortIndex = REG_DWORD 4 
Indexed = REG_DWORD 0 

 

PortAddress = REG_DWORD 0xFC20 
Interrupt = REG_DWORD 5 
DosDevices = REG_SZ COM7 
InterruptStatus = REG_DWORD 0xFC40 
PortIndex = REG_DWORD 5 
Indexed = REG_DWORD 0 
 
Serial7 subkey:

 

PortAddress = REG_DWORD 0xFC28 
Interrupt = REG_DWORD 5 
DosDevices = REG_SZ COM8 
InterruptStatus = REG_DWORD 0xFC40 
PortIndex = REG_DWORD 6 
Indexed = REG_DWORD 0 
 
Serial8 subkey:

 

PortAddress = REG_DWORD 0xFC30 
Interrupt = REG_DWORD 5 
DosDevices = REG_SZ COM9 
InterruptStatus = REG_DWORD 0xFC40 
PortIndex = REG_DWORD 7 
Indexed = REG_DWORD 0 
 
Serial9 subkey:

 

PortAddress = REG_DWORD 0xFC38 
Interrupt = REG_DWORD 5 
DosDevices = REG_SZ COM10 
InterruptStatus = REG_DWORD 0xFC40 
PortIndex = REG_DWORD 8 
Indexed = REG_DWORD 0
