;
; Returns with the line and modem status in AX. Status bits returned are:
;
; In AH:
; Bit 0 = RDA - input data is available in buffer
; Bit 1 = OVRN - the input buffer has been overrun. All
; characters received after the buffer is

; Bit 5 = THRE - room is available in output buffer
; Bit 6 = TSRE - output buffer is empty
;
; In AL:
; Bit 3 = Always 1 (always return with this bit set to 1)
; Bit 7 = DCD - carrier detect

; AH CONTAINS THE LINE STATUS

; This can be used by the application to determine whether carrier detect
; (CD) is set, signifying the presence/absence of a remote connection, as
; well as monitoring both the input and output buffer status. Bit 3 of AL
; is always returned set to enable programs to use it as a carrier detect
