4. Serial Interface Control Commands
The AT Commands described in this chapter allow the external application to determine various settings related
to the BGS2T's serial interface.
4.1 AT\Q Flow Control
AT\Q allows to configure flow control on the BGS2T's asynchronous serial interface ASC0. It is strongly recom-
mended to always use RTS/CTS hardware flow control.
Syntax
Parameter Description
[0]
(&F)
Disable flow control
1 XON/XOFF software flow control
2 Only CTS flow control by ME
3 RTS/CTS hardware flow control
Notes
• When using XON/XOFF flow control (AT\Q1) in online mode, +++ should not be used while the data trans-
mission is paused with XOFF. Before entering the command mode with +++ the paused transmission should
be resumed using the XON character.
• For compatibility reasons, the AT\Q command can be used in Multiplex mode, though the settings will not
take effect. However, be aware that whenever you use the AT\Q write command in Multiplex mode and then
save the current configuration to the user profile with AT&W, the changed AT\Q setting will become active after
restart.
