Interpreting CR-LF Codes in records
Ir-Transfer Utility C DLL interprets all characters 00h to FFh as data, but it usually interprets
CR-LF codes in records as a record separator. If a record in a data file to be transmitted
contains CR-LF codes, the Ir-Transfer Utility C DLL divides the record according to the
record separator as follows.
