Cause: End of transmission response to a message. For the 2780 terminal, one of the
following occured: equipment check, buffer overrun or parity error, synchronization check,
misfeed, jam, or component selection error. This error message can also result from one of the
following problem program errors:
· The 2780 terminal receives a block of text in excess of 169 characters.
· The HT character is used in text beyond the last stop position for the printer.
· The problem program selects a component of the 2780 terminal that is not ready.
· The 2780 terminal receives a record, while in transparency, that does not equal the
capacity of the output; that is, 80, 120, or 144.
Note: For the switched 3275 terminal, this message is not printed when an EOT is received in
response to a message. This allows time for the application to read a status or sense message.
If a message was printed, a timeout would occur before a status sense message could be
read. BTAM, however, writes an error message in the error data set.
System Action: Processing continues.
Programmer Action: none.
Operator Action: While it is possible that programming and/or hardware problems can cause
this error, it is probably the result of an operation problem at the terminal. Depression of STOP
on the printer or punch, a full chip box, a forms check, etc. will cause this message to be
If the problem persists, the terminal location should seek local hardware support.
