Description
ACC-24E2S Communications Checksum: With I4=1 or 3, Turbo ACC-24E2S computes the checksum for communications in either direction and sends the checksum to the host. It is up to the host to do the comparison between ACC-24E2S’s checksum and the checksum it computed itself. Turbo ACC-24E2S does not do this comparison. The host should never send a checksum byte to Turbo ACC-24E2S. Host-to-Turbo-ACC-24E2S Checksum: Turbo ACC-24E2S will compute the checksum of a communications line sent from the host to Turbo ACC-24E2S. The checksum does not include any control characters sent (not even the final Carriage-Return). The checksum is sent to the host immediately following the acknowledging handshake character ( or ), if any. Note that this acknowledging and handshake comes after any data response to the command (and its checksum!). If Turbo ACC-24E2S detects an error in the line through its normal syntax checking, it will respond with the character, but will not follow this with a checksum byte.
Turbo-ACC-24E2S-to-Host Checksum: Turbo ACC-24E2S will compute the checksum of any communications line it sends to the host. This checksum includes control characters sent with the line, including the final . The checksum is sent immediately following this . On a multiple-line response, one checksum is sent for each line. Note that this checksum is sent before the checksum of the command line that caused the response. For more details on checksum, refer to the Writing a Host Communications Program section of the manual. Serial character errors: If Turbo ACC-24E2S detects a serial character error, it will set a flag so that the entire command line will be rejected as having a syntax error after the is sent. With I4=0 or 1, it will also send a character to the host immediately on detecting the character error. Note that this mode will catch a character error on the as well, whereas in the I4=2 or 3 mode, the host would have to catch an error on the character by the fact that Turbo ACC-24E2S would not respond (because it never saw a ).
