[comp.dcom.modems] X.21 Leased Circuit Service

fff@mplex.UUCP (Fred Fierling) (11/11/89)

The X.21 spec allows two methods of synchronizing call control characters
between DTE and DCE; one using SYN characters and one using the byte timing
interchange circuits.  Can anyone tell me which of these two methods is most
often used in Europe?
