V.25 bis Autodialer (External Modem Only)

Transcription

1 V.25 bis allows dialing functions to be controlled using synchronous data. You select V.25 bis through the appropriate &M command. Note The modem must be configured as V.25 SDLC ASCII NRZ for use with an AS4 IBM computer (&M5). SOFTWARE GUIDELINES An indicator enclosed in less than/greater than signs represents a specific character in the appropriate character set, ASCII or EBCDIC. <sp> - space Each response below is considered an individual message by V.25 bis conventions. For example, a dial command with intermediate call progress enabled (BISYNC mode ASCII/EBCDIC character set) is: From computer To computer <sy><sy><stx>crn<sp>(25)555-24<etx> <sy><sy><stx>val<etb> V.25 bis commands can be in one of these data formats: ASYNC BISYNC SDLC NRZ SDLC NRZI in ASCII or EBCDIC Access these formats using: &M Asynchronous dial/asynchronous data &M Asynchronous dial/synchronous data &M2 Dials stored number when DTR off/on transition is detected/sync data &M3 Manual dial/sync data &M4 V.25 bis dialer/bisync protocol/sync data (ASCII) &M5 V.25 bis dialer/sdlc protocol/sync data (NRZ) &M6 V.25 bis async dial/sync data &M7 V.25 bis async dial/async data Motorola 336 BPS Fax Modem 53

3 DIAL PARAMETERS The parameters used in autodialing are listed below. The memory available for dialing can hold up to 4 characters. If you insert spaces or other parameters not listed, like as dashes, those characters are not counted. Character Function through 9 DTMF and pulse digit * and # DTMF digit : Wait for dial tone W Wait for 2nd type of dial tone > Pause for second = Pause for 3 seconds < Pause for programmed delay time P Pulse dialing T Tone dialing & Flash (go on hook) for <Insert equation here> second ; PARM separator Space, dash, parenthesis, Characters inserted for readability only period Motorola 336 BPS Fax Modem 55
