MSCOMM doesn't deal with files - it sends and receives character streams. You'd have to write the file out to MSCOMM32 using the Output property.

buffer = FILETOSTR('Label.txt')
oComm.output = buffer

will work with small files, or you can use low-level file I/O to read a line at a time from the file and stuff it out the control - you'll need to make sure to send CR/LFs if you read a line at a time from the file.
