VRf: loosing characters during RS-232 data collection

Question asked by VRFuser on Feb 20, 1998
Hello,

I am collecting data from multiple COM ports. I have 3 Digi Xem Systems
(AccelePorts) PORTS/16em. (50 com ports). In HP VEE 4.01, I switch from
com port to com port, reading a sentence from each. Sometimes I loose
serveral characters from the beginning of a sentence.
This is true if I read characters or strings.

9600 baud
8 data bits
no parity
1 stop bit

Direct I/O
.35 second timeout
end string with newline character

4096 byte buffer
byte ordering MSB
no handshaking

Any suggestions would be greatly appreciated.

Thank You,
