A Telnet session may be established to port TCP 23, allowing remote control
of the SPCe in the same way as serial communications link. Once the Telnet
session is established, commands may be issued in the format:
spc <two-digit command code> <optional parameters>
For example, to set the pump size to 1200 using the command
CMD_HV_SET_PUMPSIZE, issue the following command in the Telnet session:
spc 12 1200
Unlike the serial command protocol, no opening tilde, no address field, and
no checksum are required. It is important that the command code be two
digits. For example, command code 1 must be issued as 01.
