Serial Interface
The printer's optional LocalTalk/Serial interface can be set for
either RS-232C or current loop operation. The data format
settings can be changed using SelecType; see Chapter 3 for
information on changing SelecType settings.
Note:
When using the serial interface as RS-232C, the availability of baud rates
over 38400 depends on your computer's hardware reliability (including
the interface cable). When using the serial interface as current loop, the
availability of baud rates over 2400 depends on your computer's
hardware reliability (including the interface cable). EPSON does not
recommend or guarantee the use of any particular brand of computer.
Handshaking
The printer's optional LocalTalk/Serial interface can use DTR
(Data Terminal Ready) signal levels and XON/XOFF
communication protocols either separately or in combination.
When the vacant area for data in the input buffer drops to 256
bytes, the printer outputs an XOFF code or sets the DTR signal
level to low (MARK), indicating that it cannot receive more data.
