Serial Port with 16550...

HAYES sells a serial port called ESP(tm) which stands for Enhanced Serial 
Port.  This IBM compatible serial port comes with two DB-9 serial ports and 
uses the 16550A.  You can configure the ports for any COMx (x=1 to 9), and any 
IRQx.  You can also program the ports for FIFO or DMA mode.  In DMA mode, a 
processor on board does all the work and frees up the computer's 
microprocessor, therefore allowing for multitasking and incresed throughput.  
The ESP can also be configured for RTS/CTS or DTR/DSR hardware flow control.

For more information, please contact Hayes Customer Support at (404) 449-8791.
