mscomm buffering
[231 byte] By [jtabish] at [2007-11-11 9:58:43] 
I'm trying to use mscomm to read a 18KB image off a smartcard that comes in 1 continuious stream. I'm not sure exactly how to go about doing this properly. Please give suggestions. I should also note the stream is in hex.

Ok here is my codeinpBuff = vbNullString
Do Until frmMain.MSComm.InBufferCount = 0
DoEvents
inpBuff = inpBuff & frmMain.MSComm.Input
Loop
This gets me a length of 1840 chars which I need double that amount back so just trying to figure out a better way. I do not have a way of determining the end of the data transmission either.
