Transaction Commands

PH - PRINT COMPACTED TRANSACTIONS WITH HOST INTERACTION
Use the PH command to output compacted transactions (without spaces, headings, or
punctuation). With the PH command, the microprocessor sends one transaction and waits for a
response from the host computer. If the computer acknowledges the check sum of the last
transaction (received check sum agrees with received transaction characters), it transmits an A.
The microprocessor responds with the next transaction. If no more transactions are available, the
Series 1000 displays an asterisk in response to the last A command. If the computer does not
acknowledge the check sum of the last transaction (received check sum does not agree with
received transaction characters), it transmits an X. The microprocessor responds with the same
transaction. If the computer desires to terminate the PH command before all transactions are
sent, it transmits an E.
