4.1.8 Telnet Server Mode
LS110 supports Telnet COM Port Control Option (RFC2217 compliant) so that user can control serial
parameters like baud rate, data bits and flow control option using his local RFC2217-compliant Telnet
client program. (Please refer to 4.2 Serial port Configuration for more detail information about serial
parameters)
Usually this option is used with the RFC2217-compliant COM port redirector so that user can control
parameters of serial ports of LS110 using his serial port application program. For this purpose, SENA
OEM version of Serial/IP from Tactical Software, LLC is bundled with LS110. Please refer to
documentations of Serial/IP for more detail information about using the COM port redirector.
