You can tune the performance of the Serial Service by using Regedt32 to navigate to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Serial
The following Value Names are all type REG_DWORD entries:
| Value Name | D e s c r i p t i o n |
| ForceFifoEnable | A 1 enables FIFO (First In First Out buffer on your UART chip), a 0 disables it. If you want to enable FIFO for selected Serial ports, add these Value Names to the Parameters/Serial# sub-keys instead. |
| LogFifo | A 1 enables FIFO notification at start up, a 0 does not. |
| PermitShare | A 1 allows Serial ports to use the same IRQ. |
| RxFIFO | Using the Decimal Radix, set the number of character that the FIFO receive buffer can accumulate before generating an interrupt. The default is 8 and the maximum is 14. If you do not have a very fast processor, limit this number to 12. |
| TxFIFO | Using the Decimal Radix, set the number of character that the FIFO Transmit buffer can accumulate before generating an interrupt. The default is 1 and the maximun is 16. 16 works well on a dual processor or a fast uni-processor. |
