Description

maxinplen

Maximum number of bytes to preview

Details

The length of returned data is limited by one of the three factors, whichever is smaller: the amount of data in the RX buffer itself, capacity of the receiving string variable, and the limit set by the maxinplen argument.

Since string variables can hold up to 255 bytes of data, this method will only allow you to preview up to this number of bytes.
