However, if you store the output in a byte, you won't be able to distinguish EOF from the DEL (Delete) character. (Actually a non 0 value, as there are any number of reasons not to succeed, but usually only one success case.) When getchar() returns -1 it is clearly not returning a character. The value of -1 is often used as false/invalid/fail indicator on Unix/Linux. A valid character while will have a value in the range 0 to 255. Extension of Time (EOT) Request Form Date this form was completed: In evaluating an Extension of Time (EOT) request, The Graduate School considers several factors, including history of forward progress toward the degree and currency of knowledge in the field of study. When the serial transmission ends, the file driver reports this as an EOF (End Of File) condition.ĮOF is not a character. Serial connections are usually accessed using a file driver. On a serial connection an EOT (End Of Transmission) character indicates a desire to end the transmission. Additional control characters are used for transmission control and error correction. These include characters such as SOH, STX, ETX, FS, RS, GS, and, US. There are a number of other control characters which are related to transmission of data over serial lines or storage of files on a serial source like paper tape.

EOT is one of a number of control characters used by seerial devices.
