Communication Services Break Handler Window

If the application detects an error condition and you are running one of the terminal-based access methods, the Communication Services Break Handler window appears with one or more of the selections shown in The Communication Services Break Handler Window. This window also appears if you issue a break signal while any communications access method is executing.

For example, if you are running the EHLLAPI access method and you specify a LIBNAME or a FILENAME statement for a file that does not exist on a remote host, you are notified of this problem by the Communication Services Break Handler window.

The Communication Services Break Handler Window

[IMAGE]

When the Communication Services Break Handler window appears, you can control what happens next by selecting specific actions from a menu. The selection items in this window differ across access methods, but the functions that are provided are the same for all access methods. These functions are:

c continues processing of the command or the program that was running when the break signal was issued or when the host message was interrupted.

k disconnects the link and aborts processing of the RSUBMIT, the SIGNON, or the SIGNOFF command.

d invokes the debugger.

r re-sends the last information that was transmitted over the link. Information travels over the link in units called packets. Occasionally, a packet is lost or is garbled, and link processing stalls. When this happens, use the R command to re-send the previous packet and resume processing.

s snaps (copies) a message from a remote host screen to the local LOG window. Blank lines in the remote host screen are not copied. This command is applicable only for EHLLAPI connections. In situations where a message from the remote host causes an interruption, use this function to snap the message from the remote host into the LOG window where you can read it.
This item appears only in the window for EHLLAPI connections.

x enters the subset mode of the local host.

a invokes the Application Break Handler window.
