Hi gaoliming@byosoft.com.cn, The redundant symbol is available after using Hexedit and Edit command in the shell. I have tried these 2 commands only. These changes are required for Hexedit and Edit commands only. Thanks, Sivaparvathi C From: gaoliming Sent: Tuesday, September 13, 2022 12:22 PM To: devel@edk2.groups.io; Sivaparvathi Chellaiah Subject: [EXTERNAL] 回复: [edk2-devel] [PATCH]Shell screen will show a redundant symbol after using Hexedit command under command line **CAUTION: The e-mail below is from an external source.

Or, is it only required in Hexedit command?
