From The x3270 Wiki

Known issues

  • Resizing or maximizing the wc3270 window makes bad things happen. Please do not do this.
  • Numeric fields do not allow the + and - characters to be entered if the numericLock resource is set to true. (Thanks to Roberto Ponti for the report.)
  • The emulator will crash if the -port command-line option is used.
  • The command-line syntax -set resource=value does not work on x3270.
  • The -e command-line option to connect to a local process does not work on x3270.
  • Cross-compiles using recent versions of MinGW warnings about printf formats.



  • Unified the two ways of running Windows tests under the script.
  • If the host sends a TELNET WONT TN3270E (even if it has never sent WILL TN3270E) and the emulator is in TN3270E mode, the emulator will cancel TN3270E mode and send WONT TN3270E. This is not listed as a bug fix because it is a workaround for a bug on the host side, which should be sending DONT TN3270E.
  • Added the retry resource to retry host connections, even if the reconnect resource is not set to true.
  • Added more validations for bad host writes and pop-ups to report them.



Bug fixes



  • Fixed a c3270 crash when a connection is opened from a remote source (HTTP server or script port) while at the c3270> prompt.
  • Fixed a c3270 crash when the -secure and -trace command-line options are used together.
  • A key typed into a full field in insert mode no longer overwrites the character under the cursor.
