The SunHSI/S software ships with its own version of the serial port utilities. In general, the SunHSI/S utilities provide a superset of the features described in this chapter.

  • Page 44: Software Port Names

    Software Port Names The port naming conventions are used by initialization and serial port diagnostic commands. Software port names for SunHSI/S ports are of the form hihN, where N is a number in a range starting with 0 and ending at one fewer than the number of serial ports on your machine.

  • Page 45: The Hsi_Init Command

    The hsi_init Command The hsi_init command allows you to display and modify some of the hardware operating modes common to high speed serial lines. These features make the hsi_init command valuable when troubleshooting and repairing problematic serial link lines. Other applications also use the hsi_init command. For example, some applications use the hsi_init command to initialize serial ports, and the hsi_loop command (described in “The hsi_loop Command”...

  • Page 46: Table 4-3 Hsi_Init Parameter Values

    To set these parameters, use the syntax hsi_init portname keyword=value. For example, to set the maximum transmission unit (mtu) parameter of port hih2 to 1000 bytes, you would type: # hsi_init hih2 mtu=1000 displays the possible values for each of these hsi_init parameters, and TABLE 4-3 lists the default values as initialized by the SunHSI/S driver for each port.
  • Page 47 speed The speed parameter sets the line speed, or baud rate, of the serial line in bits per second. You can set this parameter to be from 0 to 2048000 bps. In most situations, the actual line speed is determined by the modems in use, not by the Sun hardware, so the speed set by hsi_init is used only for compiling performance statistics for the hsi_stat command (see “The hsi_stat Command”...
  • Page 48 NRZI data encoding does a voltage transition when data is absent (voltage level 0), and it does not do a voltage transition (no return to 0) when data is present (voltage level 0). With NRZI, the data is decoded using relational decoding.

  • Page 49: Table 4-4 Hsi_Init One-Word Commands

    mtu/mru The mtu parameter sets the packet size of the maximum transmission unit, and the mru parameter sets the packet size of the maximum receive unit. By adjusting these parameters, you may achieve better performance out of the link. Both of these parameters can be set between 1 and 1600 bytes.

  • Page 50: The Hsi_Loop Command

    The hsi_loop Command The hsi_loop command performs a loopback test that checks the following components of your communications link: Port-driver software layering CPU-to-port communication Correct operation of the serial port Cable from port to modem (or modem equivalent) Local and remote modems (or modem equivalents) Transmission line When you invoke hsi_loop, it runs the hsi_init command to initialize the serial port and send out packets.

  • Page 51: Table 4-5 Hsi_Loop Options

    The options for hsi_loop are described in TABLE 4-5 hsi_loop Options TABLE 4-5 Option Parameter Name Description packet count Specifies the number of packets used for data transfer. The default is 100. packet length Specifies the length of the packet in bytes. The default is 100; the maximum is 1600.

  • Page 53: Test Option 4 - Use Previously Set Mode

    With test type option 3, hsi_loop treats both local and remote modem loopback testing the same, since clocking is provided by the modem in both cases. Whether the data is looped back through the local or remote modem depends on how the modems are set up.

  • Page 54: Hsi_Loop Output

  • Page 55: The Hsi_Stat Command

    The hsi_stat Command The hsi_stat command gives you information about the packets transmitted and received on a synchronous serial line. The hsi_stat command is a valuable tool for monitoring your serial link. The syntax for hsi_stat depends on whether you want to display the statistics of a single port or a number of ports.

  • Page 56: Table 4-6 Hsi_Stat Statistic Descriptions

    describes the statistics in the hsi_stat output. TABLE 4-6 hsi_stat Statistic Descriptions TABLE 4-6 Statistic Description Reports the line speed as set by hsi_init It is the system speed administrator’s responsibility to make this value correspond to the modem clocking speed when clocking is provided by the modem.

    - transmit clock signal rxc - receive clock signal The effect of the default settings for all of these parameters is that SunHSI/S 3.0 software does not invert the data or clock signal controlled by the parameter. To invert a signal, you specify a setting of the form param_name=-paramname, for example, txc=-txc.

  • Page 74: Inverted Settings

    Inverted Settings The reason for inverting data signals is distinct from the reason for inverting clock signals. The background for data signal inversion is explained first, then the background for clock signal inversion is explained. Data Signal Inversion The requirement for inverting data signals arises from the “ones density” problem you encounter with most T1 transmission lines in North America.

    for data transmission, which means that 12.5 percent of the bandwidth of the T1 line is wasted. When you consider that the lease cost for a coast-to-coast T1 line can be exceedingly expensive, this waste of bandwidth can be unacceptable. There are alternatives.
  • Page 76 When using long cables or cables not carrying a clock signal, a phase shift may occur causing a high number of errors. In such cases, inverting the clock signal may correct the phase shift. You may also need to invert the clock signal when connecting a SunHSI/S port to equipment not adhering to the RS-334 standard.

    A P P E N D I X hsi_init Options for Operating Modes This appendix describes the operating modes that can be set by the hsi_init utility (see “The hsi_init Command” on page 29 for instructions on how to use this utility). The SunHSI/S driver operates in two main operating modes, the high-level data link control (HDLC) mode and the IBM (SDLC) mode.

  • Page 78: Ibm (Sdlc) Mode

    IBM (SDLC) Mode This mode is designed to support IBM system network architecture (SNA) communications. It uses most of the same protocols used in HDLC mode, with two major exceptions: When the line is idle, instead of sending flag bytes, the transmitter is disabled. The request-to-send (RTS) and clear-to-send (CTS) signals are used to gate transmission.
  • Page 79 IBM Multi-Point Mode In a multi-point configuration (mode=ibm-mpt), more than two stations “share” a link. This configuration is accomplished by designating one station as a primary station and the rest as secondary stations. In this mode, the port acts as a secondary station.

  • Page 81 A P P E N D I X Hardware Functional Description This appendix contains a detailed description of the hardware block diagram ) in Chapter 1. FIGURE 1-2 SunHSI/S provides four synchronous serial communications channels for any slave host. Each channel can operate at a maximum speed of 2.048 Mbps, and each supports a separate RS-449 interface.
  • Page 82 An internal four-channel DMA provides full-duplex operation for both ISCC serial channels. Bus utilization is optimized by incorporating the internal packet status FIFO and the internal DMA, which reduces host intervention. Dual-Ported 32 Kbyte Random Access Memory The use of dual-ported random access memory (RAM) minimizes bus contention between the host and the serial controllers.

    EPROM SunHSI/S supports up to 32 Kbytes of read-only memory. This EPROM is only used for supplying the required ID string of data that begins at location zero of the physical address for the slot in which the SunHSI/S adapter is installed. Status Buffers A buffer is used to report the status of the CF signal (Receive Line Detector) from the DCE.

  • Page 85 This autoconfiguration feature is provided in the Solaris software and it is also supported in the SunHSI/S 3.0 driver software. After the autoconfiguration, the module is unloaded. The driver module is loaded to the system again when the driver is first referenced.
  • Page 86 External Interfaces The SunHSI/S 3.0 driver provides a streams-based interface to the Solaris kernel and user program. The driver software can be reached from user program through standard open(2), close(2), putmsg(2), getmsg(2), and ioctl(2) system calls.

  • Page 91 Packet Transmission and Reception When an upper-protocol layer or a user program has a packet ready for transmission by the interface, it calls either the putnext(9F) utility or the putmsg(2) system call to pass the packet to the SunHSI/S driver. If the SunHSI/S driver transmission buffer is empty, the hih_wput routine of the driver copies the packet into the RAM buffer on the SunHSI/S adapter.
