mscomm error RRS feed

  • Question

  • I am using vb6 and mscomm control to send message with AT commands. I have used many brands usb modem working fine. the old modems are working ok but if I use any of the new modem the error "Error reading com device" occurs at code line "mscomm.output". I have searched a lot on net but found no solution. Everybody says that this is a Microsoft windows problem, but in my case I do not think so because old usb modems are working successfully in any of the windows upto windows10. What wrong with the new modems, Can any one help me   thanks in advance
