I am trying to access the Siemens RuggedComm 900W ROS (operating system associated with the Ethernet switch) by establishing a serial port connection.
I have followed the instructions described in the configuration manual - https://cache.industry.siemens.com/dl/files/218/109737218/att_1028764/v1/C79000-G8976-1280_ROS_v4.3_RS900W_ConfigurationManual.pdf starting on page 33 under establishing console connection.
As the instructions say, I open a terminal on my Ubuntu machine and then physically connect the computer to the Ethernet switch using an USB to Serial Port cable (RS232). I then use sudo journalctl --follow and determine that the serial port is identified as ttyUSB0.
I then configure the serial port, resulting in the following parameters:
speed 57600 baud; rows 0; columns 0; line = 0; intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; discard = ^O; min = 1; time = 0; -parenb -parodd -cmspar cs8 hupcl -cstopb cread clocal -crtscts -ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl -ixon -ixoff -iuclc -ixany -imaxbel -iutf8 opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt echoctl echoke -flusho -extproc
I then run the command export TERM=VT100 to set the terminal id to VT100. I am expecting the login form to appear, but it does not. I have tried unplugging the USB to Serial Port and reconnecting.
