They are full duplex and *standard*. Indeed - if you don't mind spending the money now, the Telebit 2500 provides 3-2400 baud standard, 9600 baud V.32 and 9600/19.2K PEP (which is Telebit's half-duplex protocol spoofing scheme known as the Packet Ensemble Protocol). The unit retails for around $1500.00. You are right about the half duplex problem - it just doesn't cut it for interactive use, even though the line dynamically adjusts with the flow of traffic. The other problem is with V.32 - there is no standard way of falling back gradually below 4800 baud in the event of bad line conditions. -Eric -- ARPA: LAVITSKY@RUTGERS.EDU UUCP: ...rutgers!tstream!eric eric@topaz.rutgers.edu
