顧客顯示屏tc下控制串口

1、TCforDOS在TruboCforDOS下要通過串口發(fā)送數(shù)據(jù)，就需要知道串口地址，然后才可以向該地址#include shortSHORT;/*DATA BUFFER REGISTER /*line us register sic SHORT COM1 COM2 COM3 COM4 icSHORT portadd; /*碼voidOut_funcport,c SHORT port;char SHORT i= (i= WAITIME) (!(inp(port+LSR) & 0 x20); /* 0 x3ed /*waitTCforDOS在TruboCforDOS下要通過串口發(fā)送數(shù)據(jù)，就需要知道
