Note
a.
When the modem is optioned for an external transmit clock source (PTM ; 1), the modem should
be optioned for a fixed — not an automatic — handshake mode (e.g., select V.32 bis only [PRS
HM ; 3] instead of V.32 bis automatic [PRS HM ; 2]). The modem will then handshake only at
the speed given to it by the DTE.
b.
For 1200 bps V.22 operation, select PRS HM ; 7. PRS HM ; 6 is an auto mode, so setting the
DTE to 1200 bps (PRS DR ; 3) will not force the connection to 1200 bps.
