Modem Configuration and Profile
Modem Register Commands
The G24 holds certain data items in selected memory space, named Software Registers
(S-registers) and Modem Registers. Some of these registers are used as bitmaps, where one
register holds more than one data item.
All S-registers can be accessed using the S command, described in “S, Bit Map Registers” on
page 3-277. Some registers can also be accessed using dedicated commands, detailed below.
V, G24 Response Format
This command determines the response format of the data adapter and the contents of the header
and trailer transmitted with the result codes and information responses. This command also
determines whether the result codes are transmitted in a numeric or an alphabetic ("verbose")
form. The text portion of information responses is not affected by this setting.
The following table shows the effect that setting this parameter has on the format of information
text and result codes.
