Serial Channel

Usage

dp_connect serial -device serDev -block bBlock -readonly bRead

Comments

serDev is the Tcl-DP name of the given serial port. In order to make Tcl-DP scripts as portable as possible, DP names the serial ports "serial1", "serial2", "serial3", etc. The DP name is then translated internally to the OS specific name (COM1, /dev/ttyb, etc).

• bBlock is a boolean that determines whether the serial port will block while waiting for input. The default is true.
• bRead is a boolean that determines whether the serial port will be opened with readonly access. Often, UNIX serial ports are writable only by the superuser. If this is the case, using this flag will at least allow one to possibly read from the serial port. The default is false.

Options like baudrate, parity and character size can be set using fconfigure after the channel is opened.

Examples

dp_connect serial -device serial2

dp_connect serial -device serial1 -readonly true
