Slave Response
Timeout (msec) Enter a value between 20 and 5000 milliseconds. The

The Following Only Appear when Modem is Selected
RTS TX Delay (msec) Enter a value between 0 and 2000 milliseconds. The
default is 0. This delay occurs between the asserting of
RTS and the transmission of the first character of data.
RTS Off Delay (msec) Enter a value between 0 and 2000 milliseconds. The
default is 0. This delay occurs between the last data
character transmitted and the deasserting of RTS.
CTS Timeout (msec) Enter a value between 0 and 2000 milliseconds. The
