Regardless of the state of the XON/XOFF mode, the TCS can stall and unstall the host only after
two-way communication of control codes is established. Two-way communication of control
codes occurs when multidrop operation is disabled, multidrop is enabled and TCS is addressed
individually, or when multidrop is enabled and TCS 1 is addressed in broadcast mode.

 

6WDORVW

When XON/XOFF mode is on, the TCS stalls the host by sending an XOFF code and switching
the SRTS line to off. When XON/XOFF mode is off, the TCS stalls the host by switching the
SRTS line off. The TCS stalls the host when any of the following conditions exist:

•

 

The TCS input buffer is 75% full and the next code received is not a communication control
code. This is the first warning.

•

 

The TCS input buffer is 100% full, the buffer has not yet overflowed, and the next code is
not a communication control code. This is the second warning.

If additional codes are received while the input buffer is full, the TCS does not stall the host
again. However, communication control codes do not overflow the input buffer; they are
received and processed even while the input buffer is full. Any other code received while the
input buffer is full is ignored by TCS.

•

 

The host addresses the TCS for two-way communication and the TCS input buffer is 75% or
more full. This applies when a TCS not addressed by two-way communication is addressed
individually or when TCS is addressed in a broadcast mode.

•

 

The TCS address is changed to RS232 or RS422, the TCS was not addressed for two-way
communication, and the input buffer is 75% or more full.

When XON/XOFF mode is on, the TCS unstalls the host by switching SRTS on and sending an
XON code. When XON/XOFF mode is off, the TCS unstalls the host by switching the SRTS line
on. The TCS unstalls the host when any of the following conditions exist:

•

 

The TCS has emptied its input buffer and the host was previously stalled due to a filled TCS
input buffer, but the user has not stalled the host by pressing Ctrl/S.

•

 

A Reset command has been completed and the TCS is ready to receive input from the host.

•

 

When the TCS performs an acknowledged disconnect or mandatory disconnect as part of the
multidrop protocol and it had previously stalled the host. Multidrop protocol is described
later in this chapter.

•

 

When the multidrop address is changed, if the TCS was previously addressed and had stalled
the host.

•

 

The host addresses the TCS for two-way communication using multidrop protocol and the
TCS input buffer is less than 75% full. This applies when a TCS that is not addressed for
two-way communication is addressed individually or when TCS 1 is addressed in broadcast
mode.
