SUBROUTINES/METHODS

esn_to_hex

Converts a Decimal ESN to Hex. If an invalid ESN is used, it will throw a warning and return to 0.

esn_to_dec

Convert a Hex ESN to Decimal. If an invalid Hex ESN is used, it will throw a warning and return 0.

esn_valid

Check to see if the ESN looks like a valid ESN, either Decimal or Hex. If it looks like a Decimal ESN, it returns "dec". If it looks like a Hex ESN it returns "hex". If it doesn't match either it returns 0

esn_is_hex

If ESN appears to be Hex, return 1, else return 0. A valid Hex ESN is 8 digits in length, 00000000 to FFFFFFFF inclusive.

esn_is_dec

If ESN appears to be Decimal, return 1, else return 0. A valid Decimal ESN is 11 digits in length, with the first three digits between 0 and 255 inclusive and the last 8 digits between 00000000 and 16777215 inclusive.
