V IIF 1,1 NM IICONTROL CHARACTERS AND SEQUENCESProgramming note: For more detailed information on binary synchronous communicationsconventions, refer to General Information Binary Synchronous Communications, OrderNo. GA27-3004.The following table shows the control characters and sequences for BSCA:Name Mnemonic EBCDIC ASCIIStart of heading SOH SOH SOHStart of text STX STX STXEnd of transmission block' ETB ETB ETBEnd of text' ETX ETX ETXEnd of transmission' EOT EOT EOTEnquiry' ENQ ENQ ENQNegative acknowledge' NAK NAK NAKSynchronous idle SYN SYN SYNData link escape DLE DLE DLEvIntermediate block character ITB IUS USInitial program load 2 IPL DC1 DC1 ENQ.Even acknowledge' ACK 0 DLE (70) DLE 0Odd acknowledge' ACK 1 DLE/ DLE 1Wait before transmit-pos. ack l WACK DLE, DLE;Mandatory disconnect' DISC DLE EOT DLE EOTReverse interrupt' RVI DLE@ DLETemporary text delay TTD STX ENQ STX ENQTransparent start of text 3 XSTX DLE STXTransparent intermediate block 3 XITB DLE IUSTransparent end of text 3 XETX DLE ETXTransparent end of transmissionblock 3 XETB DLE ETBTransparent synchronous idle 3 XSYN DLE SYNTransparent block cancel 3 XENQ DLE ENQTransparent TTD 3 XTTD DLE STXData DLE in transparent mode 3 XDLE DLE DLENotes:1. These control characters and sequences cause a COD (change of direction) interruptionrequest to the System/7 after the required action has been completed,if the chaining flag is off.2. IPL sequence is [SEL] DC1 DC1 ENQ. SEL (address) required on multipointnetwork only. Not applicable in ASCII format.3. Transparent mode is not available in ASCII.8-4 GA34-0003
The function of each control character follows.MnemonicFunctionSOH or STX Reset control mode and set the adapter to text mode.ETB or ETX Reset text mode with block check character (BCC) comparison.EOT End of transmission.ENQ Reset text mode without BCC transmission and comparison.NAK Negative response to a request for a reply, or to a block ofheading, or a block of text in error.SYN Transmitted automatically by the adapter to establish and maintainsynchronization.DLE Alert the adapter to test the next character for a defined controlsequence. In nontransparent text mode, DLE is treated as data.In transparent text mode, the transmitter adds a second DLE aftereach data DLE. At the receiver, the first DLE is stripped off anddoes not enter storage or the BCC.ITB Included in the BCC; it causes the BCC to be sent or received.IPL Control characters to decode an IPL sequence.ACK 0 Indicate affirmative acknowledgement to even blocks.ACK 1 Indicate affirmative acknowledgement to odd blocks.WACK Indicate a temporary not ready to continue/receive condition.DISC Used on switched communication facilities only, to initiate adisconnect.RVI Reverse direction of data transfer.TTD Alert the receiving station to a temporary time delay.XSTX Turn off control mode and set the adapter to transparent text mode.XITB Same as ITB, but also turn off transparent text mode.XETX or XETB Same as ETB or ETX but also turn off transparent mode.XSYN Transmitted automatically by the adapter to establish and maintainsynchronization in transparent text mode.XENQ Turn off transparent text mode.XTTD Alter the receiving station to a temporary time delay in transparenttext mode.XDLE Alert the adapter to test the next character for a defined controlsequence in transparent text mode. The transmitter adds a secondDLE after each data DLE. At the receiver, the first DLE isstripped off and does not enter storage or the BCC.Synchronization and Timing InformationThe BSCA receives strobing pulses from the modem which establish and maintain bitsynchronization. If the modem does not supply a strobe, the Internal Clock Feature mustbe installed to supply synchronization. Whichever form of bit synchronization is used, aspecific series of characters precedes each transmission in order to establish charactersynchronization.Leading Pad CharactersIf the Internal Clock feature is being used, BSCA automatically begins transmission withtwo leading pad characters (Hex 55) followed by the initial synchronizing pattern of twoSYN characters.Binary Synchronous Communications Adapter 8-4.1Fmcww■(qc rimr.P.R• Pew,
