SWC - SWITCH C COMMAND
The SWC command controls miscellaneous functions, shown in Table 4-5. The data for
this command consists of 8 ASCII bits (“0” = hex 30 and “1” = hex 31).
To execute, send the SWC command as follows:
SWC 01010101 (with data)
or
SWC (without data)
When sending data, all 8 bits must be provided. The MICR Reader will execute the
command but it will not reply. The new settings become effective immediately. To
make this command permanent, use the SA (Save) command described at the end of this
section.
If no data is sent, the MICR Reader responds with the current settings for SWC.
