Re: Qestion about how to debug OVMF with UDT on QEMU

["wang xiaofeng" <winggundum82@163.com>]

HI Michael,
   I have tried your suggestion. ttermpro.exe shows connection refused in my Win7 after command "start "Monitor" /B %TERA_TERM_PATH% localhost:20717 /nossh"
  the tool also cannot work lonely.
   Any other software or configuration should I apply?
  Thanks!
