::::::::: :: SID :: ::::::::: After a forward connect the two mailbox system are exchanging some characters which are called SID (System IDentifier). This SID is used for defining the forward protocol. Overview of basic SID: - the SID has following structure: "[f1-f2-f3]" - (-) defines the end of first field and the beginning of the next field.Felds. - f1, f2 and f3 does not contain the characters "[" or "]". - f1 is the identifier of the software. - f2 contains software specific data, e.g. the version number of the software. - f3 is a string of alphanumeric characters and defines the set of features the mailbox know. Every character defines one feature. numbers can be added after each character to define a revision number of that feature. if a number is missing, revisionnumber 0 is used be default. OpenBCM mailbox is sending the following SID: [OpenBCM-1.03-AB1D1FHMRW$] ^known features ^version number ^name of the software Following features are known at the moment: - A: ACK-Mails are generated and send - B: compressed forward like F6FBB - B1: Resume mode when doing forward like F6FBB - D: DieBox extensions - D1: block CRCs when doing forward like F6FBB - F: batch forward like F6FBB - H: hierarchical address can be handled - M: MIDs can be handled (BIDs for personal mails) - R: reject messages can be handled - W: WPROT like OE3DZW - Z: "BCMNET Loginkonzept" is handled (german citizen band) - $: BIDs (Bulletin-IDs) can be handled The Feature D is defined as following: - boardnames up to 8 characters are supported. - lifetime are send to partner mailbox system. - AutoBIN mails are supported and forwarded. - forward of Erase-/MyBBS-mails (E/M-Mails) The character D was defined by DL8HBS and means "D"L8HBS or "D"ieBox. The D-extensions are used at the moment by following systems: - BayCom/OpenBCM-Mailbox (DL8MBT, OE3DZW, DG9MHZ, DH3MB, DK2UI, DH8YMB) - Digi-Point-Mailbox (DL8HBS) - DieBox (DF3AV, DL1BDY) - jedoch derzeit teilweise ohne "D" im SID - WinGT-Mailbox (DG8NDL) - MCuT-Mailbox (DG6VJ, DG4IAD) The existens of a SID, implicated that the system can change the forward way and can handle OK/NO-commands. OpenBCM mailbox passes each received SID and searches for $ character. If the $ character is not included into SID, forward will be disconnected by OpenBCM mailbox, because systems without BID are not supported. The SID of other mailbox system can also contain: - A (F6FBB): ACK messages are known (forward command SA) - B (F6FBB): only in addition with F: Huffman-compressed S&F - B1 (F6FBB): as B, but with CRC at beginning of each mail; resume-mode added - C (CBBS): automatic clock setting (obsolet) - D (DL8HBS): boardnames up to 8 characters, CRC-16, in addition with B also compressed, in addition with B1 also better CRC - D1 (DL8HBS): as D plus block CRC-mode in compressed forward - F (F6FBB): Batch forward like F6FBB, use F6FBB syntax - H (W0RLI): system can handle hierarchical address - I (W0RLI): system can handle "zero command", a line beginning with (;) - L (G1NNA): compression like G1NNA (obsolet) - M (W0RLI): can handle MIDs (BIDs for personal mails) - R (AA4RE): reject messages can be handled - X (W0RLI): X-Forward - Y (WA7MBL): forward with YAPP protocol - $ (WA7MBL): Bulletin IDentifier can be handled; the dollar character must be the last sign in field f3! Some examples of known SIDs: [RLI-17.5-HIX$] w0rli V17.5, using BID, H-Adr., Null-commands and X-Forward. [CBBS-5.1-$] ag3f Version der rli/gyq cbbs. [MSYS-1.16-H$] wa8bxn V1.16, using BID and H-Adr. [MBL-5.14-H$] wa7mbl V5.12, using BID and H-Adr. [4RE-2.3-MH$] aa4re V2.3, using MID, BID, and H-Adr. [DP-4.10-AB1DFHMR$] DigiPoint V4.10, F6FBB & DieBox options are used.
