- You don't give much information, so I'll start with the obvious things.
-
- Have you enabled flow control on the COM port and on your modem? Are they
- both set for the same kind of flow control?
-
- The OS/2 'MODE' command allows you to specify either XON/XOFF or hardware
- flow control, but I think that both default to disabled.
-
- Most modern modems that use the 'AT' command set use &H commands to specify
- flow control.
-
- What version of OS/2 are you using?
-
- What modem are you using?
