汉字终端是一种独立主机的输入输出设备。它不仅具有汉字输入、显示和打印功能，而且还具有汉字造字、编辑和通信功能。
汉字终端与主机一般通过RS-232C以 (36) 方式传送 (37) ，因此两者之间至少应有 (38) 根连接线。汉字终端在设置通信参数时应设为 (39) ，其字模库存放在 (40) 中。

A．数据库
B．RAM
C．磁盘
D．ROM或EPROM

答案

参考答案：D

解析：汉字终端是一种独立于计算机主机的输入输出设备，它与主机一般通过 RS-232C以串行异步方式传递汉字内码。RS-232C总线标准没有25条信号线，在多数情况下主要使用主通道，对于一般双工通信，仅需3条信号线就可实现 (一条发送线、一条接收线和一条地线)。由于汉字内码(区码或位码)是8位代码，故其通信参数的设置应为8位数据无校验位。
汉字终端的字模库一般均固化在ROM或EPROM中。
