Magnetic Card Reader Operation in IrDA Mode
§ The way we handle the magnetic card data is the same as for printing data. Esc-M is sent
to the printer in the same way as any other data and the magnetic card reading data is sent
back the same way (only that it is in the reverse direction).
§ IrDA protocol has no knowledge of this at all, they are both "user data". Thus, at least in
principle, there is no need to modify anything in the IrDA Stack.
§ IrCOMM-3 wire raw is designed to deliver a single stream of "user data" in either
direction. "User data" can be the ASCII code for "A", <CR>, Esc, or anything. In our
case, "user data" happen to be Esc-M in one direction and magnetic card data in the
other.
§ IrLPT is almost identical to IrCOMM 3-wire raw, except that most people incorrectly
assume that data flows in one direction only.
§ Early printers were unidirectional; however, more are now bi-directional, like our Series
2000.
