2.4 Serial Port Configuration
Device 
assignments
The Unity 4600 has one external serial port. A “device” must be assigned once to the serial 
port, but no “device” may be assigned more than once. In addition, more than one device 
may be assigned at one time but only one device which accepts input may be assigned. (If 
multiple devices are assigned to the serial port, the port’s settings are controlled by the 
device with higher priority according to the list below.) Device port assignment and device 
configuration (see below) may be controlled only from the unit front panel and the network 
may disable this capability. The possible devices are:
1. Terminal
2. Modem (“modem” being remote terminal via modem)
3. Local COMPEL
®
4. Auxiliary Data
5. Printer (including COMPEL
®
 e-mail and reports)
Device 
configurations
When a serial port configuration command is received, the specified configuration is 
immediately stored for the specified device (e.g. for the “Terminal” device). If a serial port is 
currently assigned another device, then its output buffer is immediately flushed and the port 
re-configured. Communication is fixed at 1 start, 1 stop, and 8 data bits, with no hardware 
handshaking. No provision for software handshaking is made in this Release. The serial 
port’s behavior for each of its device types is described in the following table:
