Release Notes PN 93000311H HP-UX Realport Driver Release 1.3.2 HP-UX 10.20, & 11.x Driver Package PN 40001847H 09/06/2002 INTRODUCTION The Digi HP-UX Realport driver makes the ports on a Digi Ethernet-based Serial Product (such as a Digi PortServer) appear as though they are local HP-UX tty devices directly attached to the computer. SUPPORTED PRODUCTS Digi One RealPort Device Server EtherLite 2 EtherLite 80 EtherLite 160 EtherLite 162 PortServer 8 PortServer 16 PortServer II 16 PortServer TS 2 PortServer TS 4 PortServer TS 8 PortServer TS 16 ENHANCEMENTS The driver now provides an option to allow a FLUSH not to block, even when the RealPort-enabled Product is not accessible on the network. BUG FIXES None. KNOWN LIMITATIONS This device driver no longer supports HP-UX 10.10. Older versions of SD-UX (from 10.20) may give an error message about the data model revision of the package information, but install should still work. This driver does NOT support HP-UX 11i version 1.5 (Itanium). HISTORY 1.3.1 Changed default port settings after an open. The ports behave the same as HP's native serial ports on open. Added dinc, dgelreset, and dgipserv to the driver package. Check the respective man pages for further information. Fixed kernel panic when using driver on HPUX 11.0 64bit. Fixed possible NULL byte problem when doing a read immediately after an open. Fix an "assert" message that would occur when the RealPort daemon was killed. 1.3.0 Arbitrary integer baud rates are supported via an option in the "ditty" tool called "cspeed". The driver fully supports use of the Digi EtherLite modules listed above with this driver, including the EtherLite 80, provided the EtherLite module has been loaded with RealPort compatible firmware. 1.2.3 Installs on HPUX 11.11, also known as HPUX 11i. Works with newer units listed above. Fastbaud rate set is now: 0 - 0 50 - 57600 75 - 76800 110 - 115200 134 - 131657 150 - 153600 200 - 230400 300 - 460800 600 - 921600 1200 - N/A 1800 - N/A 2400 - 2400 4800 - 4800 9600 - 9600 19200 - 19200 38400 - 38400 Note: If you select a baud rate that a unit does not support, the results are unspecified and you will not get an error message. 1.2.2 Added support for new fastbaud rates. 1.2.1 Corrected potential device driver could crash if PortServer nodes were added and removed in a particular order. With 64-bit kernels, assign a link speed with drpadmin. Under 64-bit kernels, the RTS and DTR signals no longer toggle at awkward moments as a result of the mishandling of a standard termios ioctl. This defect affected modems because the act of running most startup "profiles" resulted in the execution of "stty". This in turn, could cause DTR to drop, which could cause modem hangups. The installation scripts have been modified to allow for installation on platforms which support both 32-bit and 64-bit kernel operation. The RealPort daemon has been modified to workaround a bug in some HP-UX 11.x C run-time libraries, which caused the daemon to fail to run against PortServers configured with an IP address instead of an IP name. You may now supply either an IP address or IP name as originally intended. 1.2.0 The device driver added 64-bit support under HP-UX 11.x. An enhanced multi-processor implementation was released in order to address intermittent deadlock issues. 1.1.1 Fixed a problem with configuration of more than 10 PortServers. Fixed a problem with a transparent print hang after significant output to the terminal device. 1.1.0 Add HP-UX 11.x support. 1.0.3 Fixed a problem where DTR dropped immediately after a modem connect causing the modem to hang up. 1.0.0 Initial Release.
