tty2com -- cannot read meta info

[slavkoja]

Hi,

i just compiled and installed tty2com driver. All seems OK, I am able to communicate with picocom and by python serial library and no errors in log. But i am not able to read meta info, as described in README:

LANG=C head -c 46 /proc/sp_vmpscrdk
head: error reading '/proc/sp_vmpscrdk': Invalid argument

The cat provides the same error message. The sp_vmpscrdk permissions:

ls -l /proc/sp_vmpscrdk
-rw-rw-rw- 1 root root 0 mar 17 15:23 /proc/sp_vmpscrdk

Kernel version:

uname -rsvo
Linux 4.14.12-2 #1 SMP Sun Jan 7 15:31:02 CET 2018 GNU/Linux

Please try this: head -c 52 /proc/sp_vmpscrdk
