  • Page 124 AUXILIARY SUMMARY FOR FAX FUNCTION A3-3 A3.3 Service Class 1 Action Commands A3.3.1 Stop Transmission and Wait, +FTS=<Time> The command +FTS=<Time> causes the DCE to stop any transmission. The DCE then waits for the specified amount of time, and then sends the OK result code to the DTE .
  • Page 125 A3-4 AUXILIARY SUMMARY FOR FAX FUNCTION The DCE shall return to command state upon loss of carrier, and send the NO CARRIER result code to the DTE. The DCE shall obey the configured flow control from the DTE. If the DTE sends any character to the DCE other than DC1 or DC3 while the DCE is in this mode, the DCE shall enter command state and send the OK result code to the DTE.
  • Page 126 AUXILIARY SUMMARY FOR FAX FUNCTION A3-5 A3.3.6 HDLC Receive, +FRH=<MOD> The command +FRH=<MOD> causes the DCE to receive HDLC framed data using the modulation mode selected in <MOD>, and deliver the next received frame to the DTE. <MOD> may have the values shown in section 1.1. If the DCE detects the selected carrier with an HDLC flag, the DCE shall send the CONNECT result code to the DTE.
