; Revision History:
;------+---------+----------+---------------------------------------------
; Rev. | Date | Author | Description
;------+---------+----------+---------------------------------------------
; 1.1 |08 May 87| Al | - made ZAS assembler compatible
; | |Heynneman | - setup for SOROC terminal codes
; | | | - default 9600 baud, cause Super Serial
; | | | won't run consistently at 19200
;------+---------+----------+---------------------------------------------
; 1.0 |13 Apr 87| Jim Lill | - created original adapting SSERIAL.ASM
; | | | and using code from MXH-AP53.ASM
