Click Add Value on the Edit menu.

Add the following value:

Value Name: MaxNcpMessageLength

NOTE: If you set the value to 0, you get the limit of 55. If you set the limit to 1, you get a limit of 1 character messages. If you set the limit to 250, you get the limit of 250 character messages.

Click OK and then quit Registry Editor.
