Hello Irmus,

Irmus>>Thanks! It work!<<

Great! I am happy that it work for you.

Irmus>> How me this do:
I have 8 bits from lpt (impuls) 10011010 how me get hex from impuls , mayby use pulsein command?<<

Your LPT port... Is it a Serial Port? or Parallel Port?

If it is Serial, you may want to use SERIN or use a built in USART. If It is a parallel, YOu will need a chip with a 8 pin Port (like portb of most chips). you will wire up your data pins directly to the portb. and send/receive 8 bits at a time.
