We have (had) something in the system called "native ASCII" support. It's support for ancient Telegraph Adapter Type II (TELE2) devices attached to the old 270X and 374X controller, and later emulated in the 9370/9221 boxes. Those things used I/O functions like PREPARE. The "OSA-ASC" could simulate one of those. Blech. No. Thanks, but no thanks. I can envision: - TN3270E connection to VM - New SYSASCII command can be issued before LOGON - CP instructs telnet server to renegotiate to line mode NVT - Telnet server connect to *CCS as it does for line mode, but with "SYSASCII" indicator - CP prompts for userid and password as usual - Upon success, CP signals telnet server to stop doing EBCDIC-ASCII translation - CP connects *CCS terminal to virtual SYSASCII console Alan Altmark Senior Managing z/VM and Linux Consultant IBM Systems Lab Services IBM Z Delivery Practice ibm.com/systems/services/labservices office: 607.429.3323 mobile; 607.321.7556 [email protected] IBM Endicott ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www2.marist.edu/htbin/wlvindex?LINUX-390
