Eric, There are three ways to do communications in Visual Basic: 1. The least practical is to use OPEN with "COMn", because it depends on the default settings the user has set, i.e., you cannot specify the baud, parity, data and stop bits. 2. The hard way is to use the Windows API calls directly. There are two or three examples of doing this in DL1 and/or DL6. (They may still be in the MSLANG forum.) 3. The easy way is to use an add-on library, such as my company's communications library. In addition to making it very easy to send and receive data, we provide many file transfer protocols including XMODEM, YMODEM, YMODEM-G, ZMODEM and CompuServe B+. As a bonus, the two versions of our product (one for QB/PDS and the other for VB) are about 95% code-compatible. That means you can move code between the two platforms with only minor changes (if any). With methods 2 and 3, you can specify the buffer size that Windows should use for capturing data.
