WANT TO KNOW IF YOU AR USING RS232 FOR INPUTING AND OUPUTING DATA VIA THE MSCOMM PORTS USING VISUAL BASIC , THE INPUT FROM THE SESOR THROUGH THE MICROCONTROLLER TO THE RS232 WHAT FORM DOES VISUAL INTERPRET AS? MEANING DOES VB SEE ZEROS AND ONES OR CHARACTERS / ASCII. I DONT HAV ETHE EQUIPMENT YET BUT I AM PLANNING AROUNG THESE COMPONENT, AS I WOULD LIKE TO BE ABLE TO MANIPLIATE THE DATA COMMING FROM THE MICROCRONTROLLER SO THAT IT STATES WITHIN A RANGE OR LETS OUT AND ALARM IF IT GOES OUT OF RANGE AMONG OTHER THINGS. ANYONE WHO CAN ASIST ME TO ANSWER MY QUESTION PLEASE REPLY. |

The MSComm control in VB will see the data as ASCII characters, just like if you were using HyperTerminal.

MSComm control allows either text (ANSI) or binary. Here's a snip from the help file for the MSComm control 'InputMode' property. **************************** The InputMode property determines how data will be retrieved through the Input property. The data will either be retrieved as string or as binary data in a byte array. Use comInputModeText for data that uses the ANSI character set. Use comInputModeBinary for all other data such as data that has embedded control characters, Nulls, etc. **************************** Eric --- In , "onmyownja" <onmyownja@y...> wrote: > WANT TO KNOW IF YOU AR USING RS232 FOR INPUTING AND OUPUTING DATA > VIA THE MSCOMM PORTS USING VISUAL BASIC , THE INPUT FROM THE SESOR > THROUGH THE MICROCONTROLLER TO THE RS232 WHAT FORM DOES VISUAL > INTERPRET AS? > > MEANING DOES VB SEE ZEROS AND ONES OR CHARACTERS / ASCII. > > I DONT HAV ETHE EQUIPMENT YET BUT I AM PLANNING AROUNG THESE > COMPONENT, AS I WOULD LIKE TO BE ABLE TO MANIPLIATE THE DATA COMMING > FROM THE MICROCRONTROLLER SO THAT IT STATES WITHIN A RANGE OR LETS > OUT AND ALARM IF IT GOES OUT OF RANGE AMONG OTHER THINGS. > > ANYONE WHO CAN ASIST ME TO ANSWER MY QUESTION PLEASE REPLY. |
