所有四個串行端口都使用位于上TRVC062105000 TRVC070938000 TRVC070938005.A的EIA-232-D驅動器和接收器，并且所有信號線都路由到I/O連接器。? 串行端口1是一個最低功能異步端口。它使用RXD、CTS、TXD和RTS。? 串行端口2和3是全功能異步端口。它們使用RXD、CTS、DCD、TXD、RTS和DTR。
串行端口4是一個全功能異步或同步端口。它可以以高達每秒64k比特的同步比特率運行。它使用RXD、CTS、DCD、TXD、RTS和DTR。它還與同步時鐘信號線接口。
板硬件將來自CD2401的DTR信號連接到連接器P2處標記為RTS的引腳。同樣地，來自CD2401的RTS被綁定到P2上的DTR。因此，在對CD2401進行編程時，當需要RTS時斷言DTR，當需要DTR時斷言RTS。
PCCchip2提供的接口允許16位CD2401出現在連續地址處。TRVC062105000 TRVC070938000 TRVC070938005.A
對CD2401的訪問必須是8位或16位：不允許32位訪問。TRVC062105000 TRVC070938000 TRVC070938005.A
英文資料：
All four serial ports use EIA-232-D drivers and receivers located on the , and all the signal lines are routed to the I/O connector. ? Serial port 1 is a minimum function asynchronous port. It uses RXD, CTS, TXD, and RTS. ? Serial ports 2 and 3 are full function asynchronous ports. They use RXD, CTS, DCD, TXD, RTS, and DTR.TRVC062105000 TRVC070938000 TRVC070938005.A
Serial port 4 is a full function asynchronous or synchronous port. It can operate at synchronous bit rates up to 64 k bits per second. It uses RXD, CTS, DCD, TXD, RTS, and DTR. It also interfaces to the synchronous clock signal lines.
The board hardware ties the DTR signal from the CD2401 to the pin labeled RTS at connector P2. Likewise, RTS from the CD2401 is tied to DTR on P2. Therefore, when programming the CD2401, assert DTR when you want RTS, and RTS when you want DTR.TRVC062105000 TRVC070938000 TRVC070938005.A
The interface provided by the PCCchip2 allows the 16-bit CD2401 to appear at contiguous addresses.
Accesses to the CD2401 must be 8 or 16 bits: 32-bit accesses are not permitted.
