usb to serial communication problem

[andrei123456]

Hello. 

I am trying to communicate with a mesytec mscf-16 module through usb ( usb to serial converter chip from fdti ) . Using hyper terminal i can connect and send commands to the module but from labview i can't use the commands . it is like the module sens back the same string i write. 

Is there any incompatibility between the fdti vcp driver and visa?

Hyperterminal sends a CR and LF with each command. You are only sending LF - the \n. In MAX, try appending \r\n. The \r is carriage return. In LabVIEW, you must right click on the string control and select '\' Codes Display or use the constants from the string palette.
