i m using PC parallel port for communication with a 8052
the logic is set as follows
8052 <--> 8255 <-->74HC245<--> 5 m cable <--> PC PPort
when i send data to 8052 i can receive it without errors
but when i receive data it makes very much error
i mean i set control port bit5 to receive a byte at data pins of bidirectional parallel port
(the received byte is not the same as sent from 8052 most of the time )

my question is ;
has anybody used PC parallel port to communicate with a microcontroller ?
how was the results ?
can you suggest me any help ?
