- I have a wuestion concerning the serial.device: I am working on a serial
- interface for a modem and I am having the following problem.
-
- When I send one or many character(s) to the serial device in question ( a ham
- radio Packet TNC) I use a DoIO CMD_WRITE request. The problem/question is this
- I though that when you do a DoIO command a message is NOT sent to the associated
- message port. Is this correct? The problem is the Packet TNC is acting like
- a Full duplex device and I can't seem to make tit work in the half-duplex
- mode.
-
- Any suggestions?
-
- Thanks in advance
