Serial Interface
The printer’s resident serial interface can be set for RS-232C operation. This
interface has the following characteristics:

Data format
Note:
When using the serial interface as RS-232C, the awailability of baud rates over 38400
depends on your computer’s hardware reliability (including the interface cable).
Also, set the XON/XOFF protocol on OFF and use DTR/DSR control. EPSON does
not recommend or guarantee the use of any particular brand of computer.

Handshaking
The printer’s default serial interface settings 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.

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.
Once the vacant area for data in the buffer recovers to 512 bytes, the printer
outputs the XON code or sets the DTR flag to high (SPACE), indicating that
it is again ready to receive data.

it is again ready to receive data.
When using a baud rate of 38400 or higher in communications, set the XON/
XOFF protocol on OFF and set both DTR and DSR on ON and use DTR/DSR
control. If the communications speed is fast, the interval for sending of XON/
XOFF signals becomes shorter and the computer may noto be able to process
them. In addition, if you have changed this setting, change the computer’s
serial interface settings also.
