1 SET Sets the communication line characteristics for a specific terminal device. Format SET device-name[:] 2 Parameter device-name Indicates the name of the device whose characteristics are to be set. The device name has the form ddcu where dd is the device code, c is the controller designation, and u is the unit number. LAN devices are specified as the name of the device that is unit 0. For example, the first terminal device on a LAN is specified as TTA0, the second as TTB0. 2 Qualifiers /ADDRESS_COMPRESSION /ADDRESS_COMPRESSION (default) /NOADDRESS_COMPRESSION Indicates whether the address and control fields are compressed. /CLEAR_COUNTERS /CLEAR_COUNTERS=(keyword,...) Determines which counters to clear when trying to resolve performance problems. The default is to clear all counters. With this qualifier, you can specify one or more of the following keywords: Keyword Description ALL Resets all counters. BAD_FCS_PACKETS Resets the count of packets with a bad frame check sequence (FCS). DATA_LOST Resets the count of lost characters that were reported by hardware. DROPPED_ Resets the count of all characters thrown away. CHARACTERS FRAMING_ERRORS Resets the count of characters with framing errors. LONG_PACKETS Resets the count of packets longer than the current maximum receive unit (MRU) setting. RECEIVED_ Resets the count of total packets received. PACKETS RUNT_PACKETS Resets the count of packets with too few characters. TOTAL_ Resets the count of all characters received. CHARACTERS TRANSMITTED_ Resets the count of total packets transmitted. PACKETS /CONNECT Sets the line parameters and binds the ASN device to the physical terminal. /ECHO /ECHO=(FAILURE=value, INTERVAL=value) Specifies the number of Link Control Protocol (LCP) echo requests and the interval between requests that must be sent without response before the line is considered down. The default number of echo requests is 0. /FLOW_CONTROL /FLOW_CONTROL=control-option Indicates the type of flow control used over the physical link. You can specify one of the following keywords with this qualifier: Keyword Description HARDWARE Uses RTS/CTS flow control. If using this control, the transmit Asynch Control Character Map (ACCM) can be 0x0, 0x0, 0x0, 0x60000000. Only valid for lines set to /MODEM or /COMMSYNCH. XON_XOFF Uses band flow control. If using this control, the (de- optimal transmit ACCM is 0xA0000, 0x0, 0x0, 0x60000000. fault) Only valid for asynchronous lines. /HANGUP /HANGUP /NOHANGUP Determines the action that occurs when a session is terminated. This qualifier notifies the ASN driver when a modem hangup is necessary due to an idle device. For example, when the last network connection is closed on a transient line that is set to /NOHANGUP, the line switches back to the terminal driver but the modem remains connected. This allows users to reaccess the line and log in without having to redial and reestablish the connection. To use this qualifier, you must have PHY_IO privilege, or the line must have TT2$M_MODHANGUP already set. /MAGIC_NUMBER_RETRIES /MAGIC_NUMBER_RETRIES=value Specifies the number of attempts made to negotiate a magic number. Magic numbers are used to detect looped back connections. If you specify 0, no negotiations are made. If you specify 255, negotiation continues until a number is found. The default number of attempts is 5. /MAXCONFIGURE /MAXCONFIGURE=value Indicates the number of configure-request packets sent without receiving a valid configure-ack, configure-nak, or configure- reject before assuming the peer is unable to respond. Specify a value in the range of 0 to 255. The default number of packets sent is 10. /MAXFAILURE /MAXFAILURE=value Indicates the number of configure-nak packets sent without receiving a valid configure-ack before assuming that the configuration is not converging. Specify a value in the range of 0 to 255. The default number of packets sent is 5. /MAXTERMINATE /MAXTERMINATE=value Indicates the number of terminate-request packets sent without receiving a terminate-ack before assuming that the peer is unable to respond. Specify a value in the range of 0 to 255. The default number of packets is 2. /MRU /MRU=size Specifies the largest packet that can be received over the line. This value is used as part of the line negotiation, and the actual MRU setting can vary. Specify a value in the range of 6 to 1500. The default packet size is 1500. /MTU /MTU=size Specifies the largest packet that can be transmitted over the line. This value is used as part of the line negotiation, and the actual maximum transfer unit (MTU) setting can vary. Specify a value in the range of 6 to 1500. The default packet size is 1500. /NETWORK_PROTOCOL /NETWORK_PROTOCOL=(protocol-name) Specifies the the protocol allowed over the link. The default network protocol is TCP/IP. /PASSIVE /PASSIVE /NOPASSIVE (default) Notifies the PPP driver how to handle the PPP connection. It can either actively initiate the connection or wait for the remote host to start the connection. /PERMANENT /PERMANENT /NOPERMANENT Determines how the link is handled when a connection is closed or lost. If you specify /PERMANENT, the link remains in place with the PPP driver in control. If you specify /NOPERMANENT, the link is treated as a transient connection, and the terminal reverts to the terminal driver. /PROTOCOL_COMPRESSION /PROTOCOL_COMPRESSION (default) /NOPROTOCOL_COMPRESSION Specifies whether the two octet protocol fields are compressed into a single octet. /RECEIVE_ACCM /RECEIVE_ACCM=mask-value Identifies the starting Asynch Control Character Map (ACCM). This mask is used by the PPP driver to negotiate the final ACCM for asynchronous ports. Specify a mask in the range of 0x0 to 0xFFFFFFFF. The default mask value is 0xFFFFFFFF, 0x0, 0x0, 0x60000000, 0x0, 0x0, 0x0. The masks are ordered from low-order longword to high-order longword. Specify the longword mask until the last mask bits are set. The remaining longwords are set to 0. With 8 longwords, there is 1 bit for every ASCII character position (from 0 to 255). The ASCII characters 0x20 through 0x3F and 0x5E cannot be quoted. /RESTART_TIMER /RESTART_TIMER=msecs Interval in milliseconds (msecs) used to time the transmission of configure-request and terminate-request packets. Expiration of the restart timer results in a timeout event and retransmission of the packet. Specify a value from 1 to 90. The default is 30 (.03 seconds), which is intended for relatively slow speed links. For smaller, faster links, specify a smaller value. /SPEED /SPEED=(input-rate,output-rate) Allows you to control the input and output speed of the line for asynchronous ports. To use this qualifier, you must have PHY_IO privilege, or the line must already have TT2$M_SETSPEED set. Specify one of the following speeds: 50, 75, 100, 134, 150, 300, 600, 1200, 1800, 2400, 3600, 4800, 7200, 9600, 19200, 38400, 57600, 76800, or 115200. If your line allows split speed, you can specify different speeds for input and output. If you only specify one speed, it is used for both input and output. /TRANSMIT_ACCM /TRANSMIT_ACCM=mask-value,... Identifies the starting Asynch Control Character Map (ACCM). This mask is used by the PPP driver to negotiate the final transmit ACCM for asynchronous ports. Specify a mask in the range of 0x0 to 0xFFFFFFFF. The default mask value is 0xFFFFFFFF, 0x0, 0x0, 0x60000000, 0x0, 0x0, 0x0. The masks are ordered from low-order longword to high-order longword. Specify the longword mask until the last mask bits are set. The remaining longwords are set to 0. With 8 longwords, there is 1 bit for every ASCII character position (from 0 to 255). The ASCII characters 0x20 through 0x3F and 0x5E cannot be quoted. PPPD> SET/PERMANENT TTA0: %PPPD-I-CONNECTTERM, converting connection on device _TTA0: to a Point-to-Point connection In this example, the SET command is setting up a permanent network connection over the serial port TTA0.
