I am currently developping a remote software application on a E4438C, I send Modulation data (in custom mode). Data sending is triggered with a bus trigger.
E4438C is connected with GPIB bus.
The issue I meet is when the application send a trigger command to the E4438C
with the following code the 4438C is triggered and send the data

While (getchar()!=0) vi.Printf(vi, "*TRG \n");// triggers each time a key is pressed, except "0"

with the following code the 4438C is not triggered

vi.Printf(vi, "*TRG \n"); triggers once

Can anyone help me please to solve my issue, I'd appreciate.
