&En Pacing (Computer-Initiated Flow Control)
n = 12 or 13
Default: &E13
Pacing is the means by which the DTE (data terminal equipment—your computer or
terminal) regulates the stream of incoming data. It is only enabled when the modem has
some form of flow control active, such as RTS/CTS or XON/XOFF. When pacing is enabled,
the modem responds to the DTE's pacing signals. When pacing is disabled, the modem
ignores any pacing signals from the DTE.
&E12 disables pacing.
&E13 enables pacing.
#Xn Number of XOFF Characters Sent
n = 0 or 1
Default: #X0
The #X command allows the modem to send either a single or multiple XOFF characters
when the modem's buffer becomes full. When the buffer is full, the next character received
causes an XOFF character to be sent. In default mode, only one character is sent until the
buffer reaches the XON level; however, it is also possible to send one XOFF character for
every character received after the buffer is full.
#X0 causes only a single XOFF character to be sent after the buffer is full.
#X1 causes one XOFF character to be sent for every character received after the buffer is
full.
