Using VI Example Basic Serial Write Read to send AT commands to Cell phone modem error 1073807360

[Silver4Runner]

I am using the NI Example VI: Basic Serial Write and Read to send AT commands to a Cell phone acting as a Modem.  I can send AT commands to this phone using Hyperterm when I select the modem driver by name in the hypert port selection field but not as com 7 which it occupies according to device manager modem properties. The basic serial vi does not show the modem driver as a selection, only ports by comX are shown. I get error 1073807360.

Have you tried to put the name you enter in Hyperterminal in the VISA resource control? If Com 7 doesn't show, you can simply type "COM 7" in the VISA resource control. Or use "ASRL::INSTR 7".


Also, make sure the connection in hyperterminal is closed, before you open the port in LabVIEW.


Hope it helps,


Wiebe.
