Description:

The Telepen symbology provides several encode mode, each having its own pair of start code and stop code. But some Telepen system don't use the start code and the stop code to distinguish between the each mode, and always use the ASCII mode's start code and stop code, the interpretation of the data as ASCII or numeric is set only by the configuration of the reading device. The property specifies which start code and the stop code will be used. It can be one of these values (defined in the pTelepen unit):

• tgAuto: Automatically select the start code and stop code base on the value of Mode property, each encode mode having its own pair of start code and stop code.
• tgASCII: Always use the ASCII mode's start code and stop code even if the Mode property is set to tmNumeric.
• tgCustom: Use the special start code and stop code.
• tgNoStop: Use the ASCII mode's start code, but don't use a stop code.
