T
TC Terminal count.
throughput rate The data, measured in bytes/s, for a given continuous operation, calculated
to include software overhead. Throughput Rate = Transfer Rate - Software
Overhead Factor.
transfer rate The rate, measured in bytes/s, at which data is moved from source to
destination after software initialization and set up operations; the maximum
rate at which the hardware can operate.
U
unipolar A signal range that is always positive (for example, 0 to +10 V).
V
V Volts.
VDC Volts direct current.
X
Xmodem functions Allow you to transfer files using a data transfer protocol. The protocol uses
a generally accepted technique for performing serial file transfers with
error-checking. Files are sent in packets that contain data from the files
plus error-checking and synchronization information.
