How can I achieve this in VB5.0. The MSCOMM control only allows serial port interfacing. Dr_Michael August 2nd, 1999, 08:02 AM As you said the MSComm Control only allows serial port interfacing. In order to control your parallel port, the only solution is to use API calls, because there is NOT such a tool. In fact, the MSComm Control what is it doing, is to call API commands. ;-) Michael Vlastos Company MODUS SA Development Department Athens, Greece Tel: +3-01-9414900 chem1 August 2nd, 1999, 08:30 AM Thanks a lot for your answer.I would appreciate if you could please point out the relevant API and how touse it since I have already Dr_Michael August 2nd, 1999, 08:41 AM There is a INPOUT32.DLL out there on net. Download it and then you can easily use two commands. I think these are: INP and OUT. I used it a long time ago and don't remember well... If you don't find this dll, email me to send you by email...
