$+AD"BV"

commands: AD to set the preamble to no characters, and BV to change the
beep volume.

Records Per Block

Purpose: Defines the maximum number of data records transmitted per block of data.
Usually files are transmitted record by record. This configuration allows you to
transmit multiple records per data block. A block of data is transmitted during
a single transmission, like an individual data record is normally.
Note: The configured option may be overridden when you use certain communications
protocols. Records Per Block will not be overridden when you use User-Defined
protocol.
You must select the communications port and protocol before you set the parameters
that define the protocol. For help, see "Communications Protocol, Configure" earlier in
this chapter.
Default: 1 record transmitted per block
12-80
The preamble can be from 1 to 25 characters.
