V.25 bis Autodialer

The separator {sep} for BISYNC is an

<etb><sp><sp><stx>LSO<sp>

sequence for the sync format (the last LSO string terminates with <etx> per V.25 bis). For synchronous bit oriented operation, each LSO string is treated as an individual message per V.25 bis.

If no parameters follow, all stored options are sent to the DTE as

LSOxxx;ooo{sep}xxx;ooo...

Each value must be padded with leading zeros so that each field has three characters. Option zero would be sent as

LSO000;000

If only an address follows the command, the single requested option is sent to the DTE as

LSOxxx;ooo

If address and count follow the command, the requested count of options starting with the specified address are sent to the DTE as

LSOxxx;ooo{sep}xxx;ooo...
