Use  this firmware on the MX5 or MX53 with a IC Smart Card add on Module for the SLE 4428/5528 Smart Cards. The three track magnetic card reader option can be turned off if desired using the setup utility.  The SLE 4428/5528 Smart Card can be written or read thru the Com port using the POSH command Set 1.0. Magnetic card data is also sent out to the virtual serial Com port  when a magnetic card is swiped on the reader. This firmware will create a serial device attached to a Com port. Use the MX5.INF install file to automatically install the appropriate Microsoft Drivers provided with the OS. The MX5 setup utility when installed will provide this INF file. No additional drivers are required. (SLE-4428)
