V.25 bis ASYNC Menu Tree

Although V.25 bis allows asynchronous data format, asynchro- nous DTE is more likely to support the AT command set than V.25 bis.

V.25 SYNC HDLC Dialing

To set the Dial Options for V.25 HDLC, choose 1=V.25 HDLC from the front panel or the VT 100 terminal (see Figure 6-8 for the menu tree). This setting provides V.25 bis messages in bit-syn- chronous format (for example HDLC, SDLC, X.25). The bit-syn- chronous format is the most commonly used by V.25 bis.

This option specifies that the characters should be 7-bit ASCII, with the 8th bit ignored (it may be either 0 or 1).
