Kan ikke få data fra com port...

Hej
Du burde kunne bruge hyperterminal, men som sagt tidligere vise kun de tegn som er tegn. Mange gange er hastighden 9600 bit / sek. 8 bit data 1 stop bit og ikke noget hardware flow.

Jeg har selv to serielle enheder til min com port og disse anvender hastigheden 9600 osv. I mine programmer bruger jeg TSerial eller mscomm.ocx . Du kan evt. finde et andet program der kan læse fra den seriale port på www.beyondlogic.org . Hvis jeg havde tiden ville jeg godt lave et lille program du kunne bruge, men tiden er knap.

Mvh

Jeg kan godt strikke et program sammen i C++, har du en C++ kompiler?

Det må du da meget gerne.. du må gerne sende den til min mail skyper_dk@yahoo.dk

Er det den rigtige com port (com1) ?
Er det den rigtige baud rate (9600)?

Yep det er det.. Men jeg tror at problemet ligger i at den ikke "modtager data" hele tiden... Skal man sætte en timer med noget refresh eller noget til at læse fra påorten hele tiden? Hvis i forstår?

Jeg synes at du skulle prøve denne:
http://www.sysinternals.com/Utilities/Portmon.html

Den bør vise alt hvad der sker på porten.

Det var en god ide Vil jeg da lige se lidt på.. Mange tak indtil videre
