Microcom 410 printer
Note: This printer defaults to 9600 baud, 8 data bits, no parity, 1 stop bit with both hardware and software flow
control. The configuration may be changed through software commands. If Xon/Xoff flow control is used, the only
signals required are RxD, TxD, and GND. If hardware flow control is used, a CTS signal is provided and an RTS
signal is required. Xon/Xoff may be disabled through software commands. This printer also has a parallel port on a
DB25 connector.
