VFP'c supported control code for write from commport and LPT same VB and VC.I suggest you use API name VBIO.DLL whict you can download some sample on UT Download name Control hardware...But VBIO.DLL support only WIN9X.
I have other rountines for control hardware with Commport only support all Win.Please visit my website http://thaisofthouse.cjb.net (Thaifox Programmer)
