Timeouts for RJE 2780/3780 Emulator
This section describes the emulator timeouts.
Receive Timeout Default is 20 seconds.
This timeout is set when the ACK is sent to the
remote. Additional communications are expected
from the remote in the form of text, EOT or
TTD. In case of a timeout a batch job aborts.
{local} <------ text {remote} Insure host sends TTD
------> ACK or change timeouts.

<------ text, TTD, or EOT
Local Timeout Default is 60 seconds.
This timeout serves to make effective use of
the line by timing between requests to the
driver. In a job when this timeout expires the
job will abort. This is the time from the
completion of a CS intrinsic until the receipt
of the next CS intrinsic call, such as
CCONTROL, CREAD, or CWRITE.
Connect Timeout: The connect timeout is the interval until the
Data Set Ready signal is provided indicating
the communications link is established. In a
session, if CONNECT=ANSWER this timeout is
disabled.
Response Timeout This is used for line bids, response to control
characters and response to text.
The response timeout is chosen when configuring
the local mode. A primary contention response
is 2 seconds; a secondary is 3 seconds. For
example, if the response from the remote is not
received within the allowable time period, the
local station sends an ENQ and waits. This is
repeated until a response is received or the
number of retries is exhausted. This timeout
is used to resolve ENQ-ENQ contention
conflicts.
Linebid Timeout Used in the RJOUT, RJLIST, and RJPUNCH
subsystem commands.
The WAIT=m,s parameter can be specified. It
applies to each data set specified in the count
field. This timeout establishes the maximum
amount of time to wait for the remote computer
to bid for the line. If the timeout is
exceeded, the command completes and the next
command executes.
Carriage Control IBM 2780/3780
A two character escape sequence, the first two characters of a record,
are the carriage control for a line printer.

These channels must be configured on the line printer to be functional.
The carriage action required by the escape character sequence is only
executed once a NL (new line) or IRS (inter-record separator) character
has been received and has caused a print cycle.
Component Selection
Provides automatic routing between list and punch output files.
The component selection character must be the first text character of the
first block of text following an ENQ and ACK0, or the first block of a
conversational reply, or the first block following an ETX block.
