Hi! I'm trying to load test a server through ICEP which seems to be a special type of TCP packet. I want to replicate that packet with the TCP Sampler, but WireShark reveals that the packet contains a set of null characters and other top-row ascii characters that JMeter can't seem to recognize.

Is there some way for me to input null characters? If there is some way to use escape sequences or send a packet in hex instead of ascii this should be possible. Or, if neither of these are possible, can anyone recommend a better way to communicate with this server? Thank you very much!
