The Sun TC01 temperature chamber I'm working with uses a 9600 Baud serial interface for control. The example Basic code I've seen for the interface inserts delays between each byte sent to the temperature chamber. I tried using the I/O Assistant (without the delays) and cannot get commands that consist of more than one character to work. I'm concluding that a delay of 100 milliseconds or so is actually required between the characters. So how can I customize the I/O Assistant generated code to fix this problem?
