10.4. Level 4 Data Output Original Format
For ISO card, both clear and encrypted data are sent. For other card, only clear data are sent.
A card swipe returns the following data:
Card data is sent out in format of
<STX><LenL><LenH><Card Data><CheckLRC><CheckSum><ETX>
<STX> = 02h, <ETX> = 03h
<LenL><LenH> is a 2-byte length of <Card Data>.
<CheckLRC> is a 1-byte Exclusive-OR sum calculated for all <Card Data>.
<CheckSum> is a 1-byte Sum value calculated for all <Card data>.
<Card Data> format is
