It is in Basic... <G>

 Port = &H3F8 ' COM1
 'Port = &H2F8 ' COM2
 'Port = &H3E8 ' COM3
 'Port = &H2E8 ' COM4
 Ni = INP(Port + 1)
 OUT Port + 1, 0
 d = INP(Port + 3)
 c = d OR &H40
 t! = TIMER
 OUT Port + 3, c
 DO: LOOP UNTIL TIMER - t! > .5
 OUT Port + 3, d
 OUT Port + 1, Ni


 Catcha Later , I'll see you on the flip side - Rob
