Is there a way to break a string into individual charachters so that it can be used to create a command string for RS-232 communication?

I'm reading a numerical string or a number from a remote device.

I then need to take this string and send these values via RS-232 to another device.

My problem is that the device I need to send the command to requires that each individual number be entered one at a time followed by a command charachter.

I know how to use the concognate string command to put the command back to the other device, but I can not figure how  to break the string from the first device into individual charachters.

Example:

I read "2.45" from the first device.  I need to beak this into "2", ".", "4","5" individually so that I can enter them back into the other device using VISA.

Also the number of charachters of the nuber I read may sometimes vary.

Example:

Instead I read "23.343" from the first device.  I need to beak this into "2", "3", ".","3","4","3" individually so that I can enter them back into the other device using VISA.

A typical command line for sending the example of "2.45" above would be m2\rm:\rm4\rm5\r

The decimal "." is replaced by ":"

If anyone knows how to do this, I would greatly appreciate the help.

Sure. Look at this. This example replicates the inter-character delay option in Hyperterminal. In order to do what you want, you just have to append the LF at the VISA Write.

An alternative mechanism uses arrays by converting the string to a byte array and interleaving the "m" and "\r" characters, and then just using a for-loop that's autoindexed. See attached example. Modify as needed.
