;;; Patch file for Kermit version 35.3
;;; Reason:
;;;  Various changes to clean up handling of SDU serial ports.
;;;  
;;;  There's a new serial-port OPEN form, SDU-SERIAL-OPEN.  This function
;;;  knows about global Kermit parameters for specifying 1) Ascii conversion
;;;  and/or 2) Xon-Xoff flow control.  These are set under Review Parameters,
;;;  and work for <new> connections.  We create new serial port streams of
;;;  the appropriate flavor.  Other options are set as before.
;;;  
;;;  Don't let user specify *image* mode with Ascii! Menu puts up error
;;;  message.
;;; Written 18-Jul-88 23:34:31 by keith (Keith Corbett) at site Gigamos Cambridge
;;; while running on Breaking Glass from band 3
;;; with System 125.6, ZWEI 125.2, ZMail 73.0, Local-File 75.0, File-Server 24.0, Unix-Interface 13.0, Tape 24.0, Lambda-Diag 17.0, Experimental Kermit 35.1, microcode 1761, SDU Boot Tape 3.14, SDU ROM 103.
