usbserial command

Name

usbserial - transfer data over USB-serial converters

Synopsis

package require Usbserial
usbserial ?devicename?

Description

This command is used to transfer data over supported USB-serial converters (FTDI, CDC, Prolific, etc.), see this reference. When no further argument is given to the usbserial command, a list of supported USB device names in the form of zero or more /dev/bus/usb/MMM/NNN device special file names is returned. When the USB device name of a supported USB-serial converter is given as argument, usbserial opens that USB device and returns a Tcl channel handle for it. This handle may be used with fconfigure, gets, read, puts, and close. The options -mode, -ttycontrol, and -ttystatus to fconfigure are supported by the channel. However, support for getting and/or setting control lines varies between different USB-serial converter chips. Note, that similar to a normal POSIX tty device an USB device name can be opened more than once simultaneously.
