The SFR04 (Sonic ranged detector?) simply outputs a pulse width. This
cannot be recognized by the COM port, it needs a micro (such as a stamp) to
put this data in RS-232 format.

An alternative it try to use the Parallel port instead and monitor the pins
for change, but don't ask me how.

Sorry,

Hi to all …..

I'm trying to interface a srf04 to my pc's parallel port using vb6
and I'm having timing problems
Dose any one has any idea or example for making it to work without
using any microcontrollers
