Usage: SPRCmd.exe command [option]
Syntax:
list List all serial ports.
list [physical]|[virtual] List physical|virtual serial ports.
set raw|telnet-bin|telnet-ascii <COM port> <host> <TCP port>
Add virtual COM port with specified number and
redirect data to specified host and TCP port:
raw - Raw data transfer protocol;
telnet-bin - Telnet Binary data transfer
protocol;
telnet-ascii - ASCII data transfer protocol.
setserver raw|telnet-bin|telnet-ascii <COM port> <TCP port> [physical]
Add server serial port with specified number
on specified TCP port:
raw - Raw data transfer protocol;
telnet-bin - Telnet Binary data transfer
protocol;
telnet-ascii - ASCII data transfer protocol.
physical - if specified COM port is hardware.
bitrateemul <COM port> on|off
Enable/disable bitrate emulation option.
fixedbaud <COM port> on [value]
Set fixed baudrate:
value: numerical;
fixedbaud <COM port> off Disable fixed baudrate.
fixedflow <COM port> on [none|hardware|xonxoff]
Set fixed flow control method.
fixedflow <COM port> off Disable fixed flow control.
fixedline <COM port> on [d:<value>] [s:<value>] [p:<value>]
Set fixed line control parameters:
d:5|6|7|8 - Data bits;
s:1|1.5|2 - Stop bits;
p:none|odd|even|mark|space - Parity.
fixedline <COM port> off Disable fixed line control parameters.
reconnect <COM port> enable:on interval:<value> cache:<on|off>
Apply automatic reconnect settings for serial
port identified by number:
COM port - 1..255, 0 - all ports;
interval: 1-99999 - interval (in seconds);
cache: on|off - enable/disable cache.
reconnect <COM port> enable:off Disable automatic reconnect.
keepalive <COM port> enable:on interval:<value>
Apply keep alive settings for serial port
identified by number:
COM port: 1..255, 0 - all ports;
interval: 1-99999 - interval (in seconds).
keepalive <COM port> off Disable keep alive for specified serial port.
accumulate <COM port> time:<on|off> <value> size:<on|off> <value>
Apply data buffering for specified serial port:
COM port: 1..255, 0 - all ports;
time: on|off <value> - set buffer length in
milliseconds (0-99999);
size: on|off <value> - set buffer length in
bytes (0-99999).
remove <COM port> Remove specified virtual serial port.
removeall Remove all virtual ports.
enable Enable all virtual ports.
disable Disable all virtual ports.

Command line usage examples:
Create virtual COM5 redirected to remote IP address 192.168.10.1, TCP port 2000. RFC2217 protocol is used for data transfer.
SPRCmd.exe set telnet-bin 5 192.168.10.1 2000
Remove virtual COM5.
SPRCmd.exe remove 5
Configure fixed settings for COM3 (Stop bits = 1, Parity = None).
SPRCmd.exe fixedline 3 on s:1 p:none
