我想在我能够确定的情况下,提出什么样的预设或充分要求,即要送交律师协会的读者。 条码阅读器可与PCUS和RS-232港口连接。 我指的是,如果我有条码(4567"<>>>>,而且我在申请中规定,它应当向条码扫描器发送像123>>>>的序号,而不是将我的条码(4567"<>)改为文本编辑,它应显示1234567”。
我如何能够这样做?
<>Update:
我需要使用第LS2208条码阅读器。 借助方案拟订指南,我得以将一种特性放在条码上,但我至少需要4(至少)。 另一种可能性是,在条码上安装3个插手,但我无法将这一方法投入使用,如果我能够这样做,那么我就应该把第4位数提一下。
如果我错了,那么我就不敢在方案上做我想要的东西? 我认为,它应当这样做:与USB/Serial港连接。 如果用户与条码读物者读物的话,其功能是。 在加以改动后,然后将其放在阅读的地方。
艾滋病毒/艾滋病 它像USB接口一样,只是像关键的板投入,或像序列投入(可调)。
Update: the four digits are a special character code. I.e. you only get one character for the four digits.
这也许不能回答你的问题,但这里却走过任何路。
我们使用从序列港读出的文号码读物(Used to be Serial, Now USA to Serial Port换算ers)。 我国的法典是在 Java撰写的,使用 Java通信标本(Reads/Writes Serial/Parallel港)。 然后,我们从Serial Port那里得到投入,将其送往Swaing Application集中关注的窗口。 由于申请可以进入有限制的渠道,我们可以改变我们想要的溪流。
