SysAdmin on large Unix machines (HP-UX, AIX, Linux, and lately solaris). I mainly work on Performance analisys and Tuning for problems related to Infor ERP LN and database (manily oracle). I also design applications and program them, currently in Java. I am absolutely unhappy with Java and I will start my next work probably in Python or Django.

comment Directory “not found” on HP-UX for NFS mount point
Thanks for the hint. Permissions for underlying directory are ok. I also discovered, while umounting and mounting it back, that the share is not NFS but CIFS. the mount command display it as NFS, still.

comment How to get name of Display Manager on Linux?
@Marco it should contain the desktop name choosen by the user at login time. If the content is default, then I think, it gets the first one in /usr/share/xsessions.

comment How do I configure my tty session such that a form feed `\f` character will clear the terminal?
@StaceyAnne and does minicom works as expected? I mean, clearing the display when receiving a formfeed?

Sadly, I have no other suggestions beside checking all serial settings.

These settings are the same as shown from your first stty command, so, yes, they seems right. Does minicom show the serial line status (connected or disconnected)? Does this status change when you disconnect the serial cable from the USB converter?

@StaceyAnne, my fault, since I tried it on a Mac, using a different sed (bsd instead of gnu). It seems that really gnu sed matches control characters. I think that this answer is the right one, then, since you may use it and filter what you read from ttyACM0 in order to translate formfeed in ansi escape sequences. Did you tried it? Does it really works as it should?

@jofel it seems that sed does not interpret control character. The following command show it: echo "\f" | sed 's/\f/formfeed received/g'. In your example it should not match the line while it matches the line.

At least, the xterm manual page at xfree86.org/current/ctlseqs.html seems to clarify the while in VT100 emulation a formfeed is translated in a linefeed.

I believe the FPGA is not sending the two characters backslash and f, but the correct control byte 0x0C.
