read-serial-port-char

Description

The function read-serial-port-char reads and returns a character from the serial port associated with serial-port.

A timeout will occur if the character is not available before the read timeout (as specified by values given when the serial port was opened by open-serial-port).

When a timeout occurs, if timeout-error-p is non-nil, then an error of type serial-port-timeout is signaled, otherwise timeout-char is returned. The default value of timeout-error-p is t.
