    Unhappy "error reading comm device" on Nokia 6020

    Am getting an error message with Nokia 6020 & CA-42 data cable while sending a message using the AT command using VB.

    MSComm1.Output = "AT+CMGF=1" & vbCrLf
    Sleep 500
    MSComm1.Output = "AT+CMGS=98401111111" & vbCrLf 'dummy mobile no.
    Sleep 1000
    MSComm1.Output = "Hello This is my test message"
    Sleep 2000
    sMsg = MSComm1.Input
    When I try to execute the above commands am getting the "Error reading comm device" error.

    Pls help me to resolve this issue.

    PS/FYI: Am able to send & receive the messages using the same AT commands with HyperTerminal.
