tserialport - tcl package for library libserialport

https://fossil.sowaswie.de/tserialport

Version 1.2 is now Tcl 9.x compatible


Description

libserialport is a minimal, cross-platform shared library written in C
that is intended to take care of the OS-specific details when writing
software that uses serial ports.
Note: While libserialport is hosted on sigrok.org (and sigrok uses libserialport), this is a completely independent library that can be
used by other projects as well.
The libserialport library does not depend on any sigrok related
libraries or projects.


Sysnopsis

Thank you for the packages you announced recently. They are nice and
unique additions to the language.

It locates the serial interfaces.

Example

tserialport::getports ?open?

Command open will try to open the port in read mode and get the default settings.

Returns a list of all serial ports at your system including the device
name and usb or bluetooth information as a dict.

package require tserialport

set mydict [tserialport::getports open]
Result example Mac OS X:

0 {
device /dev/cu.Bluetooth-Incoming-Port
description Bluetooth-Incoming-Port
open true
transport native
baudrate 9600 bits 8 parity invalid stopbits 1
cts ignore dsr ignore dtr on rts on xon_xoff disabled
}
1 {
device /dev/cu.usbserial-FT0882PI
description UC232R
manufacturer FTDI
product UC232R
serial FT0882PI
vendor_id 0x403 product_id 0x6001
open true
transport usb
baudrate 9600 bits 8 parity invalid stopbits 1
cts {flow control} dsr ignore dtr on rts {flow control} xon_xoff
disabled
}
Result example Windows:

0 {
device COM1
description {Kommunikationsanschluss (COM1)}
open true
transport native
baudrate 1200 bits 7 parity none stopbits 1
cts ignore dsr ignore dtr on rts on xon_xoff disabled
}
1 {
device COM11
description {USB Serial Port (COM11)}
manufacturer FTDI
product TTL232RG-VSW5V0
serial FTTFRFB4
vendor_id 0x403 product_id 0x6001 usb_bus 0x2 usb_address 0x5
open true
transport usb
baudrate 1200 bits 7 parity none stopbits 1
cts ignore dsr ignore dtr on rts on xon_xoff disabled
}

Ok, it's not only plain serials (rs232 et al.), but also others like
bluetooth etc

Cool, thanks!

The package helps you find all serial interfaces on the system. For
example, if you connect a USB device that can be controlled via serial
and plug it into a different port on the bus, the device will get a
different device name. You can then use the serial number of the USB
device to find the device you want to control in the returned list.

Tach Alex,

first of all, happy new year!

... You can then use the serial number of the USB

... minus these el-cheapo USB adapters lacking a serial number.
