DOS开发编程 & 发展交流（开发室） » How do I write a DOS32 keyboard simulated input program with WATCOM C++

The following is a DOS 16-bit keyboard simulated input routine, but because DOS32 does not support the pokeb and peek memory functions. Right now I need functions under DOS32 that also have this capability, but I can't convert it to functions supported by WATCOM DOS32. (Note: not WATCOM DOS16) Experts who understand WATCOM c/c++, please help me out, many thanks. void keyboard(int choice,char key) { int offset,i; offset=peek(0x40,0x1c); for(i=0;key!='\x0';i++) { if(choice==0) { pokeb(0x40,offset,0x00); pokeb(0x40,offset,key); } if(choice!=0) { pokeb(0x40,offset,key); pokeb(0x40,offset+1,0x00); } offset=offset+2; if(offset==0x3e)offset=0x1e; } pokeb(0x40,0x1c,offset); }

Could it be that no expert has shown up yet?

Use assembly to directly drive the speaker port

Under the Watcom directory there is an example directory provided by Watcom, and inside it there is a Sample that is exactly what you need. Why didn't you look for it yourself? Strange??
