If the low water value is relatively small you may find that the output buffer become empty before you write another block of data this is quite possible because unix is time sharing multitasking environment this will result in discontinuous data transmission in a timeout sensitive application e g facsimile fax transmission discontinuous data may falter the operation 61

Sometimes the application software may not be able to write any further data to the output buffer because of the output buffer being full the application has to wait until the output buffer has enough space again the criteria to tell if the output buffer has enough space is whether the output buffer reached its low water level that is the output buffer will accept further data only when the low water level is reached 61
Syntax for sco unix xenix 61
Syntax for unix svr4 61
The default low water is 512 bytes you can enlarge it but better not exceed one half of the output buffer each port s output buffer is 8k bytes 61

However users might want to control the dtr or rts signal on their will thus the rts flow control bit should be turned off hwflowcontroloff in order to take over the control of dtr or rts signal via function mtcrts or mtcdtr mtcrts and mtcdtr can be effective only after the rts flow control bit of mhwflow is turned off 63

For rs 422 485 serial communications when an electrical signal travels through two different resistance junctions in a transmission line the impedance mismatch will sometimes cause signal reflection signal reflection causes signal distortion which in turn will contribute communication errors the solution to this problem is to establish the same impedance at the line ends as in the line itself by terminating them with resistors 79

Near the receiving side 79
Rs 422 485 impedance matching 79
Stands for termination resistor near the receiving side 2 the suggested termination resistor for awg 26 cable is 100 ohm 3 the suggested termination resistor for phone cable is 600 ohm 79
The value of the termination resistor should equal the characteristic impedance of the transmission line the resistors should be added 79

It means something is wrong with driver installation or the file has been deleted accidentally or corrupted somehow to recover the file simply install the driver again 83
Shutdown the system first and refer to the problem 1 for solutions in the previous section general troubleshooting 83
The possible reason is irq or memory conflict with other isa bus adapters like lan and scsi board or system bios please refer to the corresponding problem in previous section general troubleshooting for solutions 83
This indicates moxa board is found but the irq is conflicting with other adapter please make sure there is no conflict with other adapter s irq check the pci bios irq setting first make sure irq is available 83

Region table overflow nreg1on or nproc parameter too small 85
The above error messages imply that the system resources are exhausted you should tune the kernel parameters to a larger value and rebuild the kernel to be able to accommodate the new configuration refer to unix system manual about how to tune the parameters and rebuild kernel 85
The applications are not compatible with the c218turto pcl on board line discipline the only way to work it around is to set on board line discipline feature to disable in board sub menu of advanced configuration section unix of chapter software installation 85
The possible cause is memory conflict or defective board please shutdown the system first and then refer to the corresponding problem and solutions in previous section general troubleshooting 85
