the lsudev tool in tests/ like this for me when the device is connected?
lsudev tty
Thanks!

Hi Dan,
see attachments for the 'lsudev tty' and 'modem-manager --debug' . The Modem is a Siemens TC63i connected to /dev/ttyS1 .
A minicom session looks like this (Baudrate 115200; 8N1; Hardware Flow Control: No; Software Flow Control: No;)
