\0 replaces \ in MAX

[Boilermaker10]

I'm trying to write an ENQ character to a system, testing what I'm doing in MAX before I try to code a VI to do the job.  Every time I try to send the character \ENQ (which I am given to understand is the ASCII text representation of an enquiry character), MAX instead writes \0ENQ, which I believe is interfering with my ability to gather information from the system.  Can anyone shed some light on why this happens and how to stop it?

Give a screenshot showing how you are sending this command in MAX.

try "\05" without the quotes.  thats an \=escape 05 as ASCII literal in hex
