Tauranga rangatū me tona hāngaitanga

Na ki te whakarongo ki te parau "tauranga i runga i te rorohiko", e kore koe e hiahia ana ki te haere ki toa makehe, kia te rangatira o te hangarau rorohiko ranei. I muri i te katoa, kei te pai matau ara tamariki kura tuatahi i roto i tenei mea.

I te kupu "tauranga" Kei te nuinga o māngai te tangata moenga ki cranes tiketike i reira nga kaipuke nui tomo, hua tuku me te utanga o taonga. I roto i te rorohiko engineering tāuru tauranga putanga ko tetahi o nga momo o atanga pūmārō hangaia ki te hono i te whakaaro ā-me piringa ki te raraunga pahi kaupapa. Mai te ahua o nga rorohiko tuatahi kua whakaarohia he maha nui o ngā tauranga rerekē e rerekē e rua whakatinanatanga tinana me te kawa whakamahia. Kua ora ētahi, ka e whakamahia noa i teie mahana. Hei tauira, i unsoldering ano he tauranga rangatū, he maha kaiwhakanao kaupapa i runga i o ratou hua.

He aha te mea te reira na faahiahia? Tukutahingakore tauranga rangatū (i ētahi wā ka karangatia e COM, i te reo Ingarihi. Word «Communications») puta i roto i te tuatahi tauira rorohiko IBM-hototahi. Whakamahia ki te hono kiore, pouwhanga me ētahi atu pūrere piringa, me te whakahaere (e hiahiatia ana taura null-pouwhanga), hononga whatunga ohie i waenganui i rorohiko e rua. Ko tētahi o nga painga e nohoia ana e te tauranga rangatū ko i te tapatahi o te whakatinanatanga taputapu me ngā pūmanawa.

I te pae tino, e māngai reira e tūhono 9 ranei 25-titi. tuku Raraunga e wahi i roto i te moka reira i te moka, ä (ratau, te tuarua i konei te ingoa). e kore he kaupapa ki tetahi wa rohe ki te wā i waenganui i nga 16 paraire (2 bytes) Kawa. Ngā mihi ki tenei āhuatanga, kei te te tahi mau taime i huaina te tauranga rangatū tukutahingakore.

Me kï reira e te whakaritea tonu te mōhiohio auau moka. Ko te kupu, i roto i te whakatinanatanga pūmārō paerewa, te auau 115.200 paraire whakaaetia ia te rua (mkh), ahakoa pūnaha nuinga mahi Windows te āwenewene iti reira ki 9600 (ka taea te kaiwhakamahi hanga whakatikatika ki te kaiwhakahaere pūrere). Rerekē te tahi atu atanga rangatū e kohia (USB, FireWire) paraire ki pākete, ka tuku i roto i wahi.

Kua he atanga USB noa kua whakatinanatia ki te whāinga o hono to'o 'i te mākete o hoholo tauranga COM (RS-232C). Ko tenei taahiraa mooni, mai te tere whakawhiti raraunga i roto i te momo tino hua 921,600 anake mokotare, kihai i taua nui (whakaritea ki USB me 480 Mb / s). Ko te drawback tuarua - e kore e taea ki te "wera" hononga: he whakamātau ki te hono i te pūrere ki te tauranga rangatū ina te rere hua te rorohiko i roto i te take pai ki te ngoikore ki te mahi e tika ana ki te kore o Mono & Play hangarau, a i kino rawa - ki te kore o rua te pūrere me te pūmana COM tauranga i runga i te kaupapa (kāri roha).

No te mea o tenei, i te tau i ma'iri a'e nei, kāri whakaputaina katoa e kore e whai i te tauranga COM, rite kua tupu ki PS / 2 me AGP. Heoi, he maha nui o apatoko ngā hangaia ki te mahi ki te tauranga rangatū, takoha kaiwhakanao ki toe i te COM me tae noa LPT (whakarara). He tika, kua korerotia maha kaiwhakamahi ratou "whakawhetai koe". I muri e rarapa hoki te kaiwhiwhi amiorangi he inaianei kahore he take ki te titiro mo te rorohiko tawhito ranei hoko whāurutau fiemālie, inverters. I tua atu, kei te mahi ano te nuinga o hötaka i roto i te tauranga rangatū, rite kore e te hōtaka mana tuhituhi meinga rawa nui te raruraru hoki ki a ia.

Ko reira ngā e tokomaha o te tenei ra apatoko ki te mahi tika i roto i te pūnaha whakahaere fa'ifa'itaki te tauranga COM. Tenei waea pūkoro, waerehe, te whāurutau Nihokikorangi , me etahi atu. Ko e mo'oni, te āhuatanga o te tauranga mariko he nui ki runga ake i te whakatinanatanga paerewa.
