Page 48 500 TA Option Configuration
TERMINAL INTERFACE AND PIN OPTIONS
These options affect the interface between the 500 TA and the PC or terminal.
They select the format of the data sent to the PC, and the operation of the pins
on the PC interface.
DTE Data Mode &M
An important consideration in configuring the 500 TA is the type of interface
with the PC or terminal. There are two basic types: asynchronous and synchro-
nous. The 500 TA supports an asynchronous mode (default) and two synchro-
nous modes. 500 TA operation in synchronous mode is described on
page 65 .
DTR Detect Time S25
This command specifies the time (in 0.01 second increments) that DTR must
stay low to be recognized. Also, in Sync Mode 1 (&M1) the DTR detect time is
the amount of time (in seconds) between when a call connects and when the
500 TA begins to monitor the DTR pin.
DTE Speed @P2
This command sets the speed at which the PC or terminal operates. The AT
command processor is able to detect the DTE speed and parity automatically.
