Hi !! well for some reason CD is now being detected. Win 2000 being a bugger ? Anyway, I am using an Xmodem protocol (which I am about to post a query on) this sends 128 bytes at a time then waits for a ACK or NAK response. This avoids the problems with buffer overflow. Thanks for your comments..<br />

Hi... it'll probably jump out when I debug the code but has anyone got a 'must be' answer for the fact that my CD Holding has gone low even though I have a null modem cable attached to another RS-232 device. I know the cable is OK because i have used Terminal.exe (W3.x) and it works fine....<br />
<br />
hope someone has an idea<br />

Carrier Detect dropped with Null Modem cable ?

Visual Basic is Microsoft’s event-driven programming language and integrated development environment (IDE) for its Component Object Model (COM) programming model. It is relatively easy to learn and use because of its graphical development features and BASIC heritage. It has been replaced with VB.NET, and is very similar to VBA (Visual Basic for Applications), the programming language for the Microsoft Office product line.
