The ASCII Protocol offers offers not many security mechanism to detect and correct distorted data.
Security measures at the receiver (buffer overflow etc) are seized through the flow control. If no security measures are needed the flow control can be inactive.

The ASCII protocol supports the following features by default:
- Data is send or received without any translation.
- The receiver will be receiving data until the character EOF (ASCII 26) is received.
- The sender will transmit all data in the file including any EOF characters.

The ASCII protocol module will skip the characters CR (13), LF (10), EOF (26) or NULL (0), if the corresponding bit is set.

FLAG_ASCII_STRIP_CR
Strip the character CR (ASCII 13).

FLAG_ASCII_STRIP_LF
Strip the character LF (ASCII 10).

FLAG_ASCII_STRIP_EOF
Strip the character EOF (ASCII 26).

FLAG_ASCII_STRIP_NULL
Strip the character NULL (ASCII 0).

The ASCII protocol module will take actions based on which of the following Options are set:

FLAG_ASCII_ADD_LF_AFTER_CR
Send LF after CR.

FLAG_ASCII_ADD_CR_BEFORE_LF
Send CR before LF.

FLAG_ASCII_RX_CONTINUE_ON_EOF
Dont’ stop on EOF(26). The receiver will continue receiving data even if an EOF is received. The receiver will close the file only after a Timeout. The Timeout value can be altered using the option FLAG_ASCII_TIMEOUT.

FLAG_ASCII_TX_STOP_ON_EOF
Stop on EOF (26). Sender will stop the file transfer if it encounters an EOF.

FLAG_ASCII_TIMEOUT
Changes the default timeout. If a timeout occurs the receiver will stop receiving and close the file. The standard Timeout value is set to 1 second.
