; Edit= 15 to SERVER.MAC on 4-Oct-88 by JROSSELL, for SPR #21689
;When simulating binary mode, call MTOPR%/.MOANU to not flush NULs from the
;terminal input buffer.
; Edit= 14 to SERVER.MAC on 30-Aug-88 by JROSSELL, for SPR #21876
;Correct the way INPUT-COUNT messages are processed so as not to lose the
;first character of the input buffer. Also, ensure that 1 character reads echo
;the character if necessary.
