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.
