Hello to all!
Now i want present you my fresh program:
PPT - Parallel Port Tester, with ability testing EXTERNAL inputs via data bus in BPP/EPP modes.
For test you need make special 🤣 LIHO loopback.
Here is LIHO (Low [data nibble] In, High Out) passive test loopback scheme:
2 <- 1
3 <- 14
4 <- 16
5 <- 17
6 -> 13
7 -> 12
8 -> 10
9 -> 11
15 - NC
For run PPT (DOS/3x/9x only) enter in cmdline:
ppt [278]
where 278 - hex number of base port for test, if need. Without number program will use port 0x378h.
Tested on: old ISA multicard, p3 integrated port, core i7 integrated port. Not work in ECP mode!
Wait your replies 😀
