litex_term copy+paste skips characters when pasting

[Jeremy Herbert]

Hi,

I have found myself repeatedly running mem_list in the bios, copying a line in the memory map like 0x20000000 0x800000 and then typing mem_test <ctrl+shift+v> to paste the memory region.

However, I have come across a peculiar issue in that if I use picocom to do this it works fine, but it doesn't in litex_term. Instead, it randomly skips over characters like this:

0x00000800
02000 x000
02000 08000

(each line is a separate paste)

I have confirmed by pasting into a separate application that the copy is successful, it's just the paste that has issues.

I am running litex_term /dev/ttyACM1 and connecting to a valentyusb CDC ACM port. uname -a is

Linux lattice-xubuntu 5.15.0-67-generic #74-Ubuntu SMP Wed Feb 22 14:14:39 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

and I am running on Ubuntu 22.04 with python 3.10.6

Thanks @jeremyherbert for reporting. Do you have the possibility to also do a test with a regular UART? I would first like to see if the issue is also present or if it's specific to ValentyUSB?

I did a test with a regular UART and it works fine. But I also tried to replicate the problem on the orangecrab and it doesn't have the issue. So I am going to close this for now until I can reproduce on more than one piece of hardware.
