; CREATED 10/05/85 BY ESKAY (AS ALWAYS)
; VERSION 23 AS OF 10/11/85
;
NAME ('RemDrv')
;
; ANOTHER ENHANCED TURBODOS MODULE BY ESKAY
; IN ADDITION TO THE DESCRIPTION OF T-FCN 33, REMOTE CONSOLE I/O,
; THE FOLLOWING IS NOW POSSIBLE:
; - SET/QUERY REMOTE BAUD RATES
; - REMOTE CHANNEL I/O
;
; ADDITIONAL SYNTAX: (C-REGISTER = 33)
; REG CONT FUNCTION
; D 0FE ATTACH CHANNEL IN B, RETURN A=FF=BUSY
; D 0FD DETACH CHANNEL IN B
; D 0FC SET BAUD FOR CHANNEL IN B, FROM E
; D 0FB GET BAUD FOR CHANNEL IN B, RETURN IN A
; D 0FA RETURN INPUT DATA FROM CHANNEL B,
; IF BIT 7 SET ON B, OUTPUT BYTE IN E
