S1,F13 Establish Communications Request (CR) S,H<->E,reply
Description
The purpose of this message is to provide a formal means of initializing communications at a logical application level both on
power-up and following a break in communications. It should be the following any period where host and Equipment SECS
applications are unable to communicate. An attempt to send an Establish Communications Request (S1,F13) should be repeated
at programmable intervals until an Establish Communications Acknowledge(S1,F14) is received within the transaction timeout
period with an acknowledgement code accepting the establishment.

If m = 0, it indicates that the specified OBJTYPE is unknown. If any n = 0, it indicates that the corresponding object was not
found. If any ATTRDATA item is reported as a zero-length item, it indicates that the specified attribute does not exist. If no
errors were found, p = 0.
10.6 Stream 2 Equipment Control and Diagnostics — Messages which deal with control of the equipment from the
host. This includes all remote operations and equipment self-diagnostics and calibration but specifically excludes
the control operations which are associated with material transfer (see Stream 4), loading of executive and boot
programs (Stream 8), and all file and operating system calls (Streams 10, 13). See also continuations in Stream 17.
